With things the way they are currently, I've found that I need to seriously look at what I don't/can't wear and downsize accordingly. I bought this blouse while still thinking I was a mainly Classic gal so it's not a huge surprise that this doesn't fit the aesthetic of my mostly sweet wardrobe. It claims to be a medium, but I'd say it's a small (if you want room for your bewbs). If you need me to measure anything just ask.
