The florescent neon mesh polyester spandex material is fairly stretchy, durable, and breathable. For context, im 5'5" 120 lbs usually wear M/L (Fits true to size) Im genuinely impressed with how this set has a hook eye closure and an adjustable chain detailing. The high rise thong panty has a cheeky cut design and it's actually really comfortable, easy to put on and easy to adjust. I absolutely love the florescent neon pink, and i love wearing this set even more.
