All of my VS bras are 34D, so I initially ordered these bras in size 34. When they arrived and I tried one on, it felt super comfortable, however, at the end of the day when I took off the bra, I noticed I had marks on my back and below my breasts (where the elastic band goes), a sign that the size 34 was too small (too tight) on me. I loved the bras so I went ahead and returned the size 34 and got a size 36 instead and the size 36 is beyond comfortable!!! I am NEVER wearing regular bras again. My breasts are perfectly happy in these bras! They offer the perfect amount of support, but are so comfy and sometimes I feel like I am not even wearing a bra. This is EXACTLY what I had been looking for in a bra .Please never stop making these, I will keep purchasing them for life. I am buying another pack right now!
