yeah bro,. if you had pics it would help. any tits can look nice. but without something to compare to we cant help. just do a google for dr.'s online. you'll find plenty of nice before and after pics.
If she does her research she will know that PS don't work like that a good one is going to measure/fit you and make a recomendation on what size you should be.
Go have her check out implantinfo.com and find a woman thats about her size with the boobs she wants. Bring the pic into the surgeon and tell him exactly what look she's wanting. If he or she is any good it'll be no big deal. One of the best ways for her to decide is to bring the kind of shirt she wants to look good in to a store that has a wide variety of bras. Have her put on the kind that holds its shape and put the bra on that she wants. If it looks about right buy one, take it home, fill the cups and put the clothes on over it. If she's happy with it have her bring it with her. The surgeon can fit the boobs to the bra. No big deal happens several times a day in every plastic surgery office around the country.
