練水?
Normally, I wear Speedo/TYR, around HKD 250-350.. but if u need胸墊, the style may not be so stylish or trendy.
If I go for competition, I will wear Arena or speedo...around HKD 450-600...
If you say u practice so often, u can ask your trainer, I am sure he/she knows where to buy low cost but high quality swimming suit.. mainly is from China, around $ 80.... I tried before too.
