I have had square, broad ribs all my life, and it really brings me down because they make me look and feel fat than I actually am

it makes me look abnormal! I havn't seen anyone else with these kind of ribs. I'm afraid of wearing tops without jackets because I cant hide my ribs. I'm 17 years old, and as i grow more, my ribs will look even bigger. Sometime in the future i might want to do something about it, so..
Is there anything plastic surgery wise to do about this? such as, replaceing them with smaller fake ribs?
