Nothing's more miserable than an ill fitting bra......even a correctly fitting bra is uncomfortable to me. It's one of the first things I remove when I get home at night. Ahhhhh!!! I don't think any bra should make red marks on you regardless.
VS bras have never fit me well. Even in my younger, thinner days. I went to Dillards last year and got a bra fitting. All these years I thought I was a 36B but the very nice sales lady came carrying in 32 and 34D bras after she measured me. I thought she had lost her mind but it did make a difference. She pointed out that breast tissue goes all the way under your arms and taught me the old lady trick of bending over, reaching inside and shoving everything to the middle. It made a huge difference in my comfort and fit. And I don't have red marks. Maybe you need to try a different bra fitting.
