the toiletries kit thats only for LS weekends... what makes the cut

we've got a separate "weekend" toiletries bag that lives in the cupboard between meets and only comes out for LS stuff. its got the nicer shampoo, a body wash i actually like the smell of, my proper razor instead of the manky one i use at home... but ive been wondering what other people put in theirs that they dont bother with on normal days. like is there a particular deodorant you save for nights out, a perfume that only comes out when you're meeting someone new, a different face moisturiser. or is it weird that we have a totally separate bag and most of you just chuck the usual stuff in a wash bag and go...
