This tail photographed beautifully! It is well constructed with additionally detailing that is uncommon at this price point.I am 5’4” and 130 lbs and ordered a size large since I have wider hips/butt for my size. I did have to sew a dart right above my butt because it fit a little too large, just in that one spot.Keep in mind that the tail is spandex (not scuba knit), so it will take in water which adds additional weight. For that reason, I would not recommend it as a swimmable tail, especially if you aren’t a strong swimmer. It also takes a long time to dry.The tail has a hidden zipper near the ankle that can be used to insert a monofin or to slip your feet out and “penguin-walk” somewhere. Waist has a drawstring that ties on the side and tucks in.Overall, very pleased with this purchase!
