I love em' when they look good (i.e. Molly Cavalli & Sandee Westgate) and hate em' when they look like two round blocks practically under your arms pits

Honestly I think its a really personal choice and if girl gets them done it should be because she wants them for the rest of her life to make herself feel more physically proportional and not for any other reason whether it be a guy, work, etc.
It just sucks that the good ones are so darn pricey
