Dressing differently for dates w. guys vs girls, am I fooling myself?

Okay, so I'm bi and when I go out with guys and have a date I get all girly and the whole bit curl my hair, painted nails, and perfume (cuz what guy wants to date a girl that smells like them) #wearsaxe. Now I do feel condident and good when I get dressed up... But when I go out to the club (gay club) or have a date with a girl, I find myself trying less and feeling the urge to wear a pinik guys dress shirt and rock a black skinny tie with some coach sneakers. Umm and also wear cologne. Now being in public and doing the latter makes me a little uncomfortable, I'm not sure if it's becasue it would be something comepletely new, or I am wanting to try something that isn't actually me. My sister seems to think I am "confused" after all, all the bi girls she knows dress the same for both guys and girls (girly). But my problem is I am attracted to girly girls, so idk. Maybe I'm just into girls and need to embrace my desire to wear a man shirt lol , but I also don't wanna turn guys off by possibly wearing the same shirt as them. Guys seem to like the girls in heels and dresses or in my case that's what I like too.

Soooooooo what do you guys think? please help!
