HerRoom Response: Yes, this bra requires moving up a cup size. Unfortunately, this bra is not made in a 40G(D4).

HerRoom Response: This bra is a best-seller with a very consistent fit. Looking at your order history, you are keeping bras in size 36D3 - both a band and cup size larger. This is probably the reason you feel it fits small.
