I am in my first sub sprint tri next month. I was a little anxious about what to wear. I bought larges in both tankini and shorts because I don't like really tight clothing. I am usually a medium. I am top heavy and the top fits great with a sports bra underneath. I also like the 8 inch inseam on the shorts. Now, I can just worry about the tri and not about what I am wearing. I am 5'7,135.
