Felt like a whale not a mermaid.

The costume is so cute, but I wish it fit. I bought it on sale so I am not able to return it :( I am a 38B and the top fit perfectly, however the band moves a lot so would recommend wearing pasties underneath. The booty shorts that came with it fit fine, nothing too impressive as they were kind of unflattering since it cut into my butt. The net skirt is literally so cute but it is so much smaller than the shorts. The elastic band cut into my waist a lot and its a very thick elastic with little stretch. The netting part is very stretchy though. For reference, I am a true size 12 and I bought the L-XL and could barely get the skirt up over my hips.

Size guide is not accurate

My bust is 34 inches and I ordered both S-M and M-L. The size guide says 34 in should fit in S-M. Well the edge of my nipples hand out of both of them unfortunately. If you are a 32C or ur chest goes out to 34 inches sizes S-L will not work. Also the purple fabric is very cheap feeling. The edges are ugly and white instead of purple.
