I also have a well developed chest structure from my fathers side of the family. The best way to deal with it is to avoid tight fitting tops. Some CIS women also have this issue as well as other and they have selected their wardrobe to match their body. If you were to ask your mother, I suspect she would tell you there are some things she would never wear because they don't look good on her.
Being attractive is not so much as having the right body but knowing what looks good on you. There are some years I find it difficult to buy clothes because the styles don't work for me. Other years, everything seems to work.
