Wow, That's a tough one for sure.
But you can do it. I went through the same problem myself.
I found that instead of buying online, That I replaced it by shopping in person at sales racks and Thrift Stores.
I find that I am not as compulsive when I shop this way. I can also try the items on and ser how they actually fit and look on me. Good luck, and remember,
"Yes You Can!"
