Ellen Pompeo Wears Interesting Work-Out Clothes

I don't get how some people work out in the clothes that they do. Like last week, I was in Miami and for this one particular workout, they suggest that everyone wears booty shorts. Um. I don't want to see everyone I know in booty shorts. That is way too close to a labia flash for my taste.

And then there's Ellen Pompeo. It appears she is wearing really old, dirty shoes and then an oddly slutty polyester netted bodysuit. Go ahead, check your eyes. I did say BODYSUIT.

I mean, what about all these holes in necessary? Did she purchase this from one of those "shoe stores" that caters to "exotic dancers"? Who the hell would wear this to work out? I realize she is one of the most obnoxiously thin people in Hollywood, but come on. This is just weird.
