I didn't like the binders from Underworks so much, so I ordered this:
http://www.t-kingdom.com/shopping/english/usd_page801_english.shtml Wow it's comfy and so easy to get on. I was actually expecting it to be a bit too small but it's actually a bit big. Really comfy for wearing around the house, though, and it binds better than my sports bras and is more comfortable too. I might order a size smaller for wearing out.
