I don't like tank tops.
I like being modest. I don't like thin clothes, low cut tops, short shorts or sleeves shorter than my shoulder. I like form fitting clothes, don't get me too innocent here, but I just don't see the need to flaunt any cleavage, armpit, or buttcrack.
And I have received plenty of flirts from quite handsome men, so I'm not all that bland. It just proves there's more to a woman than her skin.
