Bigger boobs?

Kenya
I've always wanted my breast to be a little bigger, I love them and feel completely comfortable in them but I hate how certain clothing looks on me because they don't really fill them in so well. I'm currently working out and I'm looking forward to lowering my body fat so I can be healthy. I'm afraid that I will lose too much fat in my chest area. I wanted to know if anyone has experienced this or has your breast gotten bigger from working out your chest? I also want to know if anyone has gotten fat transplate into their boobs, how'd it turn out ? And were you really fit when you got it done, is it possible? Or will the doctors tell you to gain some body fat? Also I wanted to ask about breast implants, what do you think is the best option to a natural looking and feeling breast ?
