bottom line... if you are below avg height, get your clothes altered so that you don't look even shorter. Stick with solids over patterns if possible and make sure you always have a defined wasteline. You want to break up your upper and lower body to maximize perception of height. This does not mean you should clash your pants /w your shirt. No baggy jeans, make sure they're not bunched up at the bottoms... avoid excessive boot cuts but a small boot cut can help the line of your leg. Keep the jeans as low cut as possible to increase the visible length of the leg and never let your shirt hang below your ass when untucked. I could go on more if anyone is actually curious
