It depends on the person and what else is going on in my life if im honest
If i have to trek a couple of hours journey on public transport like i have for previous dates i don't really bother with much ( as by the time i get there make up has smudged and hairs a mess ect)
and if im fitting in a date after a full 8 - 6 day at uni without the chance to go home then im not going to get glammed up for it, just have a breath mint and go.
Once me and the date agreed to something really casual on a saturday so it only really involved jeans and a t shirt, as it was the cinema.
I've never really done evening dates or anything really formal though but if it was that situation i'd probably dress smartly and have a shower before heading out
I dont really do make up or clothes as a person so wouldnt do anything special in that sense for a date - the person should know the true me.
