After ordering a Waterpro stringback in a different style and loving it, I came back and ordered this one as well. This suit and the other one, are so adorable and have become my new favorite suits. I love the open back, but have never been able to find a style that would have decent covereage in the butt area as well. This one has it all...nice open back with complete freedom of movement, nice high leg cut, AND, unbelievably, great covereage over the butt. This never comes together in one suit. This suit runs slightly large, I recommend sizing down one size from what you’d wear in a speedo suit. I normally wear 32 in speedo, I got 30 in this one and the fit is perfect. My only concern is whether the fabric will maintain its shape...while it is solid and well made, my experience in the past has been that any amount of Lycra tends to stretch. Not as quickly as a nylon/Lycra suit, of course, but whenever possible, I prefer 100% polyester or a 50/50 poly/pbt blend, which I’ve found can last for years. This one is 91% polyester, 9% Lycra. That 9% Lycra could stretch. Time will tell, but for now, this has become my new favorite suit. Love it!
