If I'm going out clubbing I will almost always have a short dress/ skirt, and/or some cleavage on show and often fairly tight clothing (such as bodycon dresses). This isn't something I consciously ensure I do, but the clothes that I feel confident, and like the look of myself in happen to fit that description.
No, I wouldn't wear that sort of thing in the daytime but that's kind of irrelevant, that's for the same reason I wouldn't wear office-wear to go shopping: it's about dressing for the occasion. I would, however, wear other stuff that has my legs or cleavage on show in the day like denim shorts or a v-neck t-shirt. Similarly, if I was to go a drum & bass rave I wouldn't wear the same stuff I would wear to go clubbing because:
a)It would be too impractical and mean I couldn't put my all into dancing, therefore ruining the night.
b) There isn't the same obsession with posing for the whole night in that kind of environment because, by the end of it, everyone is going to look a state.
While I do enjoy getting ready for a night clubbing and making myself feel good, it is kind of a drag, if you're having a chubby day or a bad hair day, it can kind of taint the whole evening because the focus does seem to be on looks, throughout the whole night - from my experience anyway. Even the way everyone dances in nightclubs is posey.
As for make-up, I don't think mine could ever be classed as cheap and trashy lol. I generally do spend more time and put a bit more on if I'm going clubbing but I still don't think it's even noticeable that I've put more on at the end of it, I feel like I've wasted half an hour lol. I never like to look caked in make-up.
