If you don’t want to order something online check out the enormous rack of women’s tri clothes @ Bonzai http://tribonzai.com/. Everything on the rack, shorts, suits, tops is 50% off.
There is a wide variety in material, cut, and coverage so it’s worth trying this stuff on and at 50% you can buy several different styles.
Pro-Tip: The shorts by 2XU and Zoot are nicer than most of the tankini crap out there. Sorry, I really don’t care much for the tankini style. But, I will wear the tri shorts to the pool this summer because they fit and are flattering. And God help me, I’ll wear them on the bike just for fun for rides less than fifty miles.
If you are more modest, and I applaud your good taste and decorum even though I lack both, Pearl Izumi makes a longer tri short and again, I’d be comfortable wearing it to the pool.
Bonzai rents tri wetsuits too if you’re in the market. After a week of practice it only takes 1/2 a jar of slathered Crisco to get me into it. And yes, I realize it’s like renting rubber underwear and no, I have no thoughts of spraying Luminol on it and shining a black light on it. There are some things I simply don’t want to know.
