Okay, I'm bigendred, born with the female bits. I kind of need to take care of them, too.

So I'm looking for plus sized bras. I live in a small town, with the next largest town around 100 miles away. Bra picking here are quite slim, and I just need advice, so I can order a good, comfortable one online.
Chiefly, I was looking at Underworks (since I was looking at their subsite for a binder as well, but I haven't ordered one of those yet), but I wanted to know how well the full support bras did.
Thanks for tips, I could use them!
