I love the way this suit fits me. It makes me look like a boss. But I think there might be one problem. I have big hips but am small across the chest so small is my size. But I have been informed by my husband that I get the Lululemon effect in the behind when I am riding my bike. He is probably right because you see the color of the black fabric go gray as it stretches across my backside. I have done multiple experiments to see if he is right. A poll done amongst my friends has 50% saying yes, Amy, your crack is on display. The other 50% say, girl you look hot in that suit. I don't know what to believe. I can't have my bootie all hanging out all across Miami, plus I own SIX of the trisuits and I am like, is this endemic of the fabric? Are my nalgas always on display when I am riding? Woe is me. Mediums are too baggy in the chest.
