Most lesbians I know don't dress very feminine, but don't dress like men either. They wear jeans, trousers, female shirts, blouses, t-shirts, sensible shoes and lots of fleeces.
Some people may see this as dressing like a man, but actually it is just relaxed comfortable clothing. There are very few lesbians who actually dress like a man e.g. shirt and tie.
And lots of them have short haircuts - some lesbian cuts i.e. haircuts popular amongst lesbians, but some not.
I actually don't look like a lesbian. Bobbed hair, smart trousers and blouses is my usual dress. I dress this way because I feel more comfortable like this. But I actually sometimes don't like that I don't look like a lesbian.
If, like my OH,you look like a lesbian you don't get people constantly assuming you are straight. They either thinkyou are a lesbian,or at least think it is a possibility. You get the look of recognition with other lesbians who are strangers that you see out and about. And I do think it is more of a political statemednt to actually look like a lesbian.
