If part of your "feminist" agenda is for a woman to be considered on the basis of what she does and who she is rather than how she looks, then it seems to follow you should be very careful about how you present yourself and should probably avoid appearing attractive.
strawman. what about feminism says that a woman cannot use her natural assets to get what she wants? men can be attractive in public, but women can't? why should a woman act like she's ashamed to have boobs?
