Worn once in an indoor pool. I think it's the type that doesn't need an inner layer, but I wore it over a bikini. Front zip type for easy on and off. Removable pads included. The zipper is YKK, so it opens and closes smoothly. T-shirt type, so you don't have to worry about your sides showing. Hat also included. Purchased for about 4500 yen. #Swimsuit #Gym #Gym #Swimming #Exercise #Fitness #Underwater #UnderwaterWalking #SportsSwimsuit
