hi i was a 34c and had 460cc overs.i also have 2 children and had kind of saggy loose boobs.i had mr mahdi and he told me that either 460 or 410 would be best.i had it done in december and was measured a few eeks ago in marks and spencers and i was a 32f.wen i got them done i asked to be a dd(what i imagined a dd would look like)and they are exactly how i imagined.i always thought an f cup would be so huge but they look really in proportion and everything.i was told that because i had some breast tissue already there that i could have them over the muscle and they would still look natural because he would cover the implant with my natural tissue.you would never think i had implants,they are really natural.and aparantly it is less painfull this way.hope this helps you,good luck x
