I can always tell...
Not bad, just different
From experience...
100% look better with tight sweater
80% look better in low cut blouse
70% look better in bikini (the bad ones will have a double bubble or some visible wrinkling)
IMHO only 20% look better on their back....
For Sara....i sure hope that you have fully thought this out...many potential pitfalls (assuming that you haven't done the deed yet)
remember....beauty is in the eye of the beholder
