WTB-women's tri top M

I'm being cheap and don't want to spend full price for a good tri top. If you have an extra and want to make some cash, I'm looking for a women's sleeveless tri-top, with longer torso coverage, in a size medium(or to fit a petite 5'5", 135lb woman with an average chest). I'd also like it to have at least one rear pocket. I'm not super picky on color, but it must have chaffe-free seams.
