Cute and sturdy
I'm always disappointed by swimsuits that can't handle swimming in the sea, kayaking, etc. These are great. I have a big *** and a small waist, and they fit me super well

Beautiful colours
I have had to exchange for a larger size, they are not super stretchy as I expected. So if you are between sizes go up! However the colours are fantastic
