Speedo Women's Powerflex Eco Laser Sticks Flyback Swimsuit - High Performance Competitive Swimwear for Training & Racing | Perfect for Lap Swimming, Triathlons & Water Aerobics

Normally I would order size 10/ 36 or 12/38 depending of what I need. After reading reviews ordered size up for the reason. First of all - it depends what are you looking for: swimsuit for the race / practice or wear it on the land as well. Because all the competitive swim suites stretch while wet - you need it a bit tighter at first to avoid drag in the water. So - for the race I would order my normal pant size 10 / 36; for the practice swims - size 12 /38 would be good. Since I'm a swim coach for kids - I need to wear swimsuit on land but to be ready to go in to pool - so size 14/40 is fine: not so tight but fine in the water.My hips are 40in and it fits good for me. The fit of upper part depends on you body structure but again - it depends what you need. This size fits the goal of purchase and I'd like to order this suite in different color / smaller size for swim practices.
