Just last week I was fitted at Victoria Secret as a size 36D. I tried a few on and they fit nicely but I need a nursing bra right now. I then went to Macy's and was trying on a few MotherHood bra's. The 36D was a little too small. I was bulging out the top just a little bit, so the 36DD fit fine. I ordered this Bravado Allure bra in a 36D/DD. It was pretty big and didn't fit at all. I am returning it to get a size 36B/C. Hopefully it fits. I will update my post later if I like the fit and end up keeping it. Otherwise, just wanted to let everyone know to order a size smaller than what they normally wear.
**Update**
The 36B/C fit well, however I didn't like the wire. It was uncomfortably and rubbed on my arms a little. I ended up going with the Bravado Bliss which does not have an under wire but has awesome support and extremely comfortable.
Hope that helps!
