i use this for highschool swim team every day and its great. It felt true to size and the waistband on it is nice.
Size was not standardized.
Standard of sizes are difference from other brands and other design of NIKE swimming suits. But, it has good quality.
The material it doesn't strech as much ... tehrefore I recommend a bigger size than usual. The material maybe be more resistant to clhorine but takes away flexibility. Therefore the suit does not feel great and/or comfortable. Great look but poor in comfort!
