- Reviewed in the United States on November 11, 2011My granddaughter wanted to be the little mermaid for Halloween & after reading the reviews, I decided to buy this costume. The picture does not do it justice!! It's really cute and the tail part looks like a real mermaid tail.
It does run big; I bought the 3-4 Toddler size and she is @40 lbs. & wears 5T clothes. It was the perfect length (she's @42 inches high). It fit snug, but on our cold Halloween night she was able to wear a fleece long-sleeved top & pants in dark purple underneath due to the stretchiness of the costume's knit fabrics. To my surprise it didn't look "lumpy" or bulked up at all - it looked fabulous!!! Very graceful & lovely on my g-daughter.
I would caution though that it's a lightweight costume, you can see through it in the leg area and it needs pants or leggings or tights underneath it. Also some of the green "sequins" fell off in the leg area over time, but I didn't notice it unless I looked closely. Also, the tiara is poorly made, but we used a separately-purchased Ariel crown and jewelry set with the seashell necklace that sings instead.
All in all, a terrific-looking costume!!
- Reviewed in the United States on October 8, 2011This is a very pretty costume! As soon as it arrived, my daughter wore it for a couple of hours. I appreciate that it's not Disney -- just a nice, general mermaid costume. It's often cold on Halloween where we live, so I was excited for the long sleeves and full coverage. It does run big, as others have said. My daughter usually wears a 6X up to a 7/8, depending on how things are cut. I got her the 4-6X, and it's perfect. Others have said the shells fall off the headband. This is true. I plan to glue them in place with my favorite craft glue (Aleene's). The tail sweeps the ground, as a mermaid's tail should. I have a little concern about it getting stepped on/dirty, but I think having feet showing underneath would ruin the mermaid look. We might pin it up a bit. The tail is very sparkly, and I appreciate that the bottom is lined with something stiff so it will be a bit stronger and keep its shape. The boa comes separately, and you should get it -- it's an especially nice one.
- Reviewed in the United States on November 2, 2013Very cute costume! It definitely runs on the larger side - it was worn by my taller than average 4 year old, and we got the 3-4 size. The bigger size would have been too big, even though she wears 5 in tops and 4/5 in bottoms. She is 44" & 36lbs for reference. Mom wore the adult version of this California Costumes mermaid costume and dad was King Neptune - we all got tons of compliments! The bottom of the tail was reinforced with some stiff fabric interfacing, so it stayed flared - the mom costume did not have this feature, it was more flowy. Since she was a Sea Princess and not 'The Little Mermaid' we chose a wig to coordinate with mom's wig - the Monster High Lagoona Blue wig. (www.amazon.com/gp/product/B004UUHCNO/ref=oh_details_o05_s00_i00?ie=UTF8&psc=1) We just used a seam ripper to cut out the 'fins' and then removed the flower so she could wear her crown. The costume is thin, like most costumes, and would have been too cold for our area, so we layered a long-sleeved pink tee underneath - looked great!
- Reviewed in the United States on December 16, 2015This costume is so cute! My daughter loved it when she saw it. I was a little worried about this costume holding up after some of the reviews, but it did the trick the entire Halloween season. My daughter (3 yo) wore it to 5 different events including going trick or treating. Some of the sequins did fall off during the rough play times, but you could barely tell because there are so many.
One thing, the costume was a little long so when she was running around the fins on the tail (the white fabric lining the inside) did get torn up by her shoes. I merely cut it off when that happened. You can probably pin the costume up to avoid it if you want to. The fin is still remained in tact, but once it got torn it was see through at the bottom, as in you could see her shoes.
Overall, cute costume, decent quality and price.
- Reviewed in the United States on October 10, 2013My daughter is 2 1/2, but is very tall and wears a size 3T-4T (mostly 4T at this point). This was her first year asking for a specific costume for Halloween, but the joy and awe when we opened the package was worth far more than I could have ever imagined. The fit and length on her is perfect, just like the picture. The tail hits he floor and stands out, thanks to some stiff fabric lining, which both looks like a tail and allows her to walk (although she does have to walk fairly slowly and I may pin the skirt a bit higher for certain events so her knees are more free to walk/climb/run/etc. The headband is adorable and seems comfortable for her, but the little shells slide around a fair amount and tend to fall down in random directions as she moves and plays. I'm sure this makes them more customize-able for a pre-fab costume and a dab of glue or something could make them stay if you wanted to go through the effort.
I was concerned about the sequins and she seems to battle a bit about being fascinated enough with them to want to peel them off, and wanting the dress to stay perfect enough to be gentle with them, so for now they are fine - even after she played with the dress on for an entire evening. The packaging specifically says to spot clean only and to absolutely not put it in the machine, which makes sense for any garment that has bits glued on. While it may not be durable enough for a daily dress-up outfit, I think it is an excellent costume for Halloween, and maybe a few extra events that may occur in the short period of time before little ones grow out of it :)

This costume was really cute and fit my 4 year old well (was too long for my 2 year old) but the sequins started falling off right away.
