/fa/ - Fashion

Pay attention to your fucking body type. Once you know your measurements (which, shame on you if you didn't know your measurements for fitting clothes) and your general shape (pear, rectangle,triangle,hourglass,apple, etc.) , you can look at and narrow down the factors that make you look like shit in some clothes, but good in other types of clothes.
Also, look at pictures, lurk around, see what kind of sillouette you want to portray. I wish the sticky expanded more on this, since sillouettes are important in determining your style.
