Note: Obviously it is difficult to "measure" without separate cups so several fields are left blank. I hope the other measurements can help!
Tried this on in a boutique and they only had 30GG which is normally far too large a cup for me but this was perfect. It leads me to believe it may run small instead of being "accommodating" as it needs to be the perfect size.. and it IS!
I have this same bra in both a 32G and a 30GG. Both fit nearly the same, but I decided to try the 30GG because I thought it would give me a bit more coverage on the top of my boobs. My boobs are tall, so I don't think this would be an issue for most ladies. I was right, the 30GG is a slightly better fit, but the 32G is still very, very wearable. I really needed more than one sports bra, and I loved the 4490 the first time, so that's what I bought the second time, too.
Excellent sports bra, but does run small. I normally wear about a 30G, but am in between sizes, with a 29 inch underbust measurement. Most ladies do best to size up a band and a cup in this one.
