I'm 5'2 with broad shoulders and big breasts, is there any procedure out there to minimize this masculine look?

You concerns would be best addressed in person. There is no treatment for broad shoulders but it is certainly possible to try to get the rest of you in proportion. You may still have enough fat even at 130lbs for a BBL. It is sometimes amazing how much fat we can find when we need to. For best results, schedule a consult with a surgeon certified by the American Board of Plastic Surgery to discuss your desires and possible options.

I think that you need to be seen in person to review your goals. If you want a BBL you need to have fat reserves.
