Welcome to the Beauty section of our forums! But first there are some rules. Now for fashion obviously you aren't going to tell someone that lime boots, a pink striped shirt, lime mini skirt, polkadot hair band, checkered belt, golden teeth fillings, and messy hair is the latest look, no one will believe you and maybe if they do you'll make them look ridiculous! The main point is to help, not to get a crack at someone falling for your horrible fashion fiesta. Kay?
UPDATE: G-sister has pointed out that some people might say certain hair colours or skin colours are ugly or bad, so no one is to be rude about that.
