3.1) This one’s an easy one. If you’re wearing two items or more of clothing, try to keep one of them tight and the other a bit looser. Attention: Even dresses have a tighter and a looser part.
3.2) If you only wear tight stuff you risk the chance of looking a tad out of place and quite vulgar if the print, colour or fitting is wrong.
3.3) If you only wear loose stuff you risk the chance of being taken for a clean homeless. Or a post-pregnant woman.
