Double the fun with sibling Halloween costumes which are spooky but sweet

For fans of Frozen this sparkling princess dress will be perfect. Plus, dressing as Elsa, the ice queen, is pretty cool for Halloween. We love that it comes with accessories, and the gloves, while they were used for keeping Elsa's powers at bay, might be useful for keeping the October chill away from little fingers while trick or treating. One reviewer said, "there are plenty of ‘Elsa’ dresses to choose from so did plenty of research before buying this one. Couldn’t be happier with the quality. Went for the smallest size for a three year old following the measurements not the age guide and it fits really well. It probably won’t last forever but it’s something kids will play in so don’t really expect it to at this price." While most reviewers are happy with the size, a few commented the train is very long, with one reviewer noting, "we had to cut about 4 inches off the purple netting at the bottom as it was far too long but nevertheless I was very pleased with it and she was delighted!"

You can't have Elsa without Anna! The two sisters take on all their adventures together and so we love this costume which will work perfectly alongside the Elsa costume. With great detailing and a bright, silky pink cape, this is ideal for an autumn evening of trick or treating. After buying it for her granddaughter, one reviewer said, "it fits her perfectly, so that she didn't want to take it off. Happy with comfort, quality, appearance, versatility and stitching." However, another reviewer added, "great dress but only hand wash. All the detail comes off in the washing machine and mesh rips."

This costumes has four pieces, an all in one, hat, gloves and moustache so your little one will look just like Mario. One reviewer said, "my 5 year old picked this for a fancy dress party and he loved it. It fit lovely. The moustache stayed on the entire time, I just had to trim it slightly but if you do it before peeling the back it's easy to do. The gloves are the only thing that we're too big. My son is tall for his age and there was still plenty of room." We also love that it zips at the back, rather than velcro which can sometimes pull open.

Mario can't beat Bowser without Luigi, and this costume will turn your little one into the perfect Luigi. Completely with hat, gloves and moustache, they will have everything they need to step into a Super Mario adventure, or at least go trick or treating. One reviewer said, "Very good sizing and material for the price of it. I have two happy children dressed as Mario and Luigi!" However, another reviewer added that there is no L on the hat.

Ideal if you have a baby Princess Peach because this costume is available from 0 months, which we love. It means that even the littlest member of your family can join in the fun. One reviewer said, "My daughter was so pleased with this dress. And the little details like the crown and gloves were really good." It also includes the crown and gloves which are super cute, however, do be aware that some reviewers found the sizing cam sup very small.

Not only is this a great witch's costume, but it lights up too which will make your little one more visible when trick or treating in the dark. We love that it includes some effective accessories such as the crooked broom and essential witch's hat. One reviewer said, "loved this costume and my daughter had great fun in it. Great quality and looked better than expected." However, some reviewers were disappointed with the lights commenting that they didn't work reliably.

Hopefully you won't have any sibling disagreements, but this is a great costume for any little frog sidekicks for witch's (or the unfortunate victim of a spell). We love that it is warm too for little ones on a cold Halloween evening.

Every witch needs a witch's cat and this cute baby romper is a lovely way to include baby in the Halloween celebrations. One reviewer said, "this is so soft and fluffy, has been perfect for the cold weather." While another reviewer added, "bought this for Halloween and it was extremely cute. The wiggle of the wee tail as she walked was well worth the money." However, one reviewer commented. "seems like good quality. Fits my 13 month old on the arms but far too short. My child is small for her age too. Size up if ordering!" We love that it has a two way zipper for easy changing and it's machine washable.

We love that these t-shirts are suitable for both kids and adults, so all the family can get involved if you want to, although these are ideal or cheeky siblings. They are simple t-shirts which is great for children who don't enjoy wearing uncomfortable costumes, instead these t-shirts can be paired with leggings for a comfortable but effective Halloween costume. One reviewer said, "it is exactly what it is described as." However, some reviewers thought the image is poor quality and will start to peel after a few washes.

With a jumpsuit, NASA logo and helmet with moveable visor, this is a great costume for wannabe astronauts and we love that it will keep them warm too. One reviewer said, "the badges on the costume are very good quality with embroidered stitching, the helmet is very good and is almost worth the price of the outfit alone," however they added, "the main zipper is not especially long which makes the outfit more difficult to get on/off." Reviewers also found the sizing to be quite small. That said, it is a great quality suit which looks realistic and will be perfect for finding aliens!

This alien costume will really stand out in a crowd, not only is it bright green but also inflatable and quite large! It will be perfect for any space-themed Halloween sibling costumes. One reviewer said, "amazing!, my friend bought this for her son. It’s brilliant 6ft tall and blows up really well. Highly recommend for any alien lover." However, some reviewers did find that the head hole is quite small with one commenting, "my daughter was so excited to receive it, it was far too big for her but the head hole was too small." Also remember that because it is inflated with a fan, which does provide over 4 hours of power, it will need batteries.

This costumes includes some great accessories such as eye mask, money bag and cap and we think it is simple but effective. One reviewer said, "I was impressed with the number of pieces this costume came with. The fit was really good and perfect value for the price." However, another reviewer did add, "the mask is a lot thinner and flimsy than shown in photo and the cap is terrible, the peak on the front is designed so it doesn't sit right and it doesn't fit to the head, will have to secure it with hair pins." That said, it is a fun costume for little ones and a reviewer added, "kids got a kick out of being robbers, filled the bag with money and jewels."

Perfect for stopping any little robbers, this costume will be popular with any aspiring police officers. We love the accessories that make it feel really realistic and we think your little ones will have great fun with a game of tag while dressed as cops and robbers. One reviewer said, "my daughter had aspiration day at school and chose to be a police officer . It is perfect and perfect price too . She was so happy going into school dressed like this." Do beware that some reviewers noted it comes up quite large and so can appear quite loose and baggy.

Not only is this costume incredibly cute, but it will make a really magical pairing with a Harry Potty costume for siblings this Halloween. We love the little envelope that can be attached to the costume for Hedwig to bring important messages to Harry. One reviewer said, "great quality, excellent fit and a perfect halloween costume", while another agreed it is "very cute." However, this is hand wash only and with all that white fabric it could quickly get grubby.

Harry Potter is a favourite costume with kids and we think this one is really cool, plus it's officially licensed and comes with glasses and wand. One reviewer said, "this is pretty nice and airy. Not too heavy. The uniform is printed onto the robes so it's not separate pieces. The details are nice and clear. It is exactly as it looks in the picture," however, they did comment that the "hood is massive." Another reviewer commented, "our 6 year old LOVES the costume. The printing on the robe looks great. We're glad that we got this instead of costumes that have actual scarves, ties, etc., because there's less to drop and lose when he's out trick or treating. The sizing is accurate and it fits perfectly."

Perfect for fans of superheroes and ideal for Halloween, your little one will have being Batman as they patrol the streets trick of treating, especially if they have a little sidekick as Robin too. We love that the costume has been tested to European safety standard, EN71, too. One reviewer said, "my nearly 3 year old grandson looked so cute in this," while another said it's "pretty expensive looking." Although, that said, one reviewer did comment, "this costume is not thick, it is light weight."

This super cute costume for Batman's little partner is a jumpsuit including cape and hat. We love that it is machine washable for convenience, especially after all that Halloween chocolate. One reviewer said, "This robin costume is perfect it’s got Velcro on the back but has poppers on the legs so easy access for nappy changes ideal for toddlers." While another added, "my little one loves this. It was a perfect fit for my 19 month old and he's big." However, some reviewers found the hat quite small, with one commenting, "purchased two of these for my twin boys - daddy went as Batman! They were incredibly cute. The hat was tiny though! Didn’t fit either of them but it didn’t detract from the outfit as a whole."

This vibrant costume is perfect for fans of Disney's Descendants and the Isle of the Lost is definitely spooky enough for Halloween. We love that this costume includes the red wig for even more effect and zips at the back for ease and comfort. One reviewer said, "my daughter has been asking for a Red costume since she watched the film. What I particularly love about this costume is that it has long sleeves and legs. Very few children's costumes seem to take this into account as children do not want to wear coats over them." Another reviewer also liked the costume saying, "my daughter loves the Descendants and was really pleased to receive this costume, especially with Halloween coming up. It fits her really well and the wig, though it's obviously not natural hair, it looks good." However, they did add that the wig sheds a little bit.

This pretty dress is perfect for any little ones who want to dress up as Bridget from Disney Descendants: Rise of Red. We love the cute pink wig too. One reviewer said, "amazing quality, wig is really good quality as well, I will be buying another for my other niece." However, one reviewer did add, "if you are expecting a costume that is bejewelled or sparkly like the picture suggests you will be disappointed because it is thin and flimsy."
