    • Supercute. Perfect fit.
Size: Small (4-6)
Love, Love Love this costume. Super cute. Fits my daughter to a T! She is petite for her age (6y/o) the small was perfect for her. Comfortable enough to walk around for trick-or-treating. Would be difficult to play in- because of the slim fit. The first one we bought came with a tear along one side seam. We did the return and the new one came. I missed the opportunity to return the torn one because of hurricane Irma. Things were crazy for our family, so I was charged for the 2nd one. Hoping tp contact the company, now that we're pretty much back to normal and I've found the box with the torn one. ... show more

    • My daughter loves it!
Size: Small (4-6)
I bought this for my two year old (will be 3 in one month) and I made sure to read the reviews before purchase about the sizing. Got her the size 4-6 small and it fits great. The tail hangs longer in the front but that doesn't bother her much and it is shaped like a dress behind it. The fabric seems to be of good quality, it is a little stretchy and it is a beautiful design. We got the blue one and overall we are very happy. ... show more

    • Very tight!
Size: Medium (8-10)
Beautiful costume and my daughter loves it but it runs very small. Well, let me elaborate - perhaps it doesn't run super small but when it runs small and is that tight then it winds up being very tight. We bought it to be used as a Halloween outfit (which we will still do) but we may have to put a small slit up the side to make it easier to walk. The dress definitely won't last long after Halloween as a dress up outfit since it is SO tight and the seams are rather flimsy. To even get into the dress I had to help my daughter and go very, very slowly. It was rather a funny situation but frustrating for my daughter. This fits a lot like a Jessica Rabbit dress. TIGHT. ... show more

    • So pretty!
Size: Medium (8-10)
I am so impressed with this costume! I purchased two of them... a medium for my thin but average-height 7.5-year old daughter and a small for my solid 3-year old daughter. Both fit beautifully and look just as pictured. The material is a shiny, vibrant blue and all the details are beautiful. The bottom portion of the tail sticks out in front of my girls so that you don't see their feet. They both manage to walk and even run (although not too fast) just fine by pulling up the front of the costume a little bit. It's a definitely favorite! ... show more

    • Very cute costume but arrived with a tear and runs small

I bought this costume for my 7 year old and ordered a medium (8-10). It runs very narrow and long. It also arrived with a tear in the side seam. We did not have time to return it, plus my daughter really loved the shinny fabric and wanted to be a mermaid that did not resemble Aerial. She ended up wearing it for Halloween and it looked cute. Be aware it runs narrow in the body. It just fit her and I was able to slide the skirt up and fasten it with a blue hair rubber band in the back to keep her tail from dragging in front of her. I included a picture of the sizing on the package, it says Medium size 8-10 for 5-7 years. ... show more

    • My girls loved them
Size: Small (4-6)
We had several Halloween events to go to, and one of them started ripping at the seams at the first one, but we were able to get through three more events without them falling apart. They're really cute they fit really well the girls love them! But as with any inexpensive costume at Halloween you get what you pay for ... show more
