This is a 4 way Stretch Fabric if you are not used to wearing swimwear we suggest you to buy one size bigger . However all swimming costumes have water retention property , which make the costume little heavy when it gets wet . We suggest to buy swimwear as per size chart even if it feels tighter than your regular outdoor clothing. In water it will be perfect .
Fabric : 100% QUICK DRYING Nylon Spandex (2 times better pull back / hold than an ordinary Polyester Spandex)
Stretch : 360 degree Stretch , offers superb fit , comfort and Freedom of Movement
Do not use detergent powder while washing the swimming wear.
