Light blue and transparent see-through leotard swimsuit. Only tried on once. Color: Blue系 (Blue-based) Size: Adult M~L The size can be adjusted quite a bit with the string on the back. Also, the size can be adjusted with the ribbons on both hips. It might slip down if you don't have a certain amount of bust. - The transparent see-through parts are directly see-through. See photos 5 and 6. - The crotch button is removable, making it easy to use the restroom, etc. - The colors in photos 1, 8, and 9 are closest to the actual product. How about wearing underwear and using it for gymnastics or swimwear? Thank you for looking.
