No, only disappointment in myself on those occasions I didn't manage to rise to the occasion as I felt I should've done. I can always see how to do it, and then the challenge is, Can I manage that each and every day?
When you have a gown, there's much more to be concerned about. Where is this crease falling? Are you making a weird shape with the dress? Are you doing the designer justice? With a bathing suit, it's more about you and the mood you convey.
