I don't mean to judge, we are casual Californians and don't really GAF if someone is offended when we wear the same pair of jeans two days in a row, as long as they're clean. In most cases, you don't see people two days in a row.
Due to size restrictions, you might be better off shipping or buying cosmetics locally rather than dragging them along.
All this is very dependent on your agenda, I hope you have a wonderful trip!
