A binder is a shirt or vest that is worn to flatten the chest.
Compression shorts shape the hips and butt to a more masculine form. They work well

And WILL, aren't they great?! I am going to wait til I cut my hair and stuff before I wear it. But I did try it on. I LOVE it. May I suggest you take a picture of you with it and post it in the gallery? I would love too see how great yours looks. I wish I could post a picture of me in mine, but once again, I'm waiting until I cut my hair to take pics.
