I love this costume. I am 5’ 3” and 140 ish pounds, I bought a small and after reading the reviews I freaked out because I thought it would be to small and not fit. Luckily it’s stretches a lot and looked perfect I have a big butt but small chest and it stretched over my butt and was nice and snug around my chest, I got a lot of compliments! It was comfy also which was a plus. It was a tad long to where the tips of the fin dragged on the ground but you could still see my shoes and walk around fine, stairs were challenging but manageable. It was sexy without needing to show a lot of skin. Overall I would definitely buy this again.Such an awesome costume! The material has a good amount of stretch to it so it hugs your curves well. I received a lot of compliment when I wore this to a Halloween party. The only downside is that, because of the mermaid-cut bottom, whenever I had to use the restroom I was forced to pull the entire costume down from the top to just under my knees because the bottom of the dress, just above the fin, was not large enough to pull up over my hips. 5 stars still though because this was a minor inconvenience to me when compared to the overall awesomeness of this costume!Love the material! Fits perfectly on me.I'm 5'3 140lbs. I'm curvy & this mermaid outfit complimented my shape. The only downside is that there was not a lot of space to walk since theBottom part is narrow! But I t's manageable :) wear heels since it will prevent bottom from dragging on floor.I bought this costume for the Mermaid Parade in Coney Island. As you can see I looked AMAZING, I'm 5'9 about 190lbs with G size breasts.... the large fit great but did stretch out by the end of night. It was a hot day lucky for me the material is comfy and breathes.Not 1 bead of sweat in sight. This costume was a showstopper...I was stopped all day for photos. Buy it you won't regret it!!FABULOUS COSTUME!!!! I am a size 14, 5’9, 230lbs and I purchased the large. It fit like a glove! It is truly a MERMAID dress, because you can barely walk! Lol! But it is definitely worth it! I just did a costume change for my birthday in order to really dance! It was a STATEMENT DRESS for my birthday! Buy it!!!I bought size Large because I'm 5'4 and currently 143 lbs with a 36DDD chest. I'm very curvy. I love this costume but it is made for tall people. You need at least 4 inch platforms if you're my size.Good looking but the fin is SO ANNOYING! It is really giant and wide. Hard to walk and move in, uncomfortable. I ended up not wearing it. If you are average height (I am 5'7") it will be way too long and needs tall platform heels.It fit great, only thing is was tight around the legs making it difficult to walk so order one size up to give yourself a little walking room. other than it was a huge hit . i got so many compliments and got to be mermaid for a day!!!!Queda espectacular! El único inconveniente es que es un poco largo (mido 1,60) y arrastraba la cola por el suelo. Lo llevé a la costurera para acortarlo y le llamó la atención la buena calidad del disfraz. No hubo problema para acortarlo, fue fácil....ma era l'ultimo. non si troverà più...Algo pequeño, no me dieron opcion de tallas
