12 Fashion Mistakes That Make You Look Older

Just because your age is increasing doesn't mean your hemline has to as well. A skirt that grazes close to your ankles may hide slightly saggy knees, but it also tends to make women look wider and frumpier. Rothman says to find the most flattering skirt length for your shape, look in the mirror and note the slimmest part of the area around your knee—right above, right below or in the middle—and that's where your hemline should hit. If you want more coverage, try a form-fitting midiskirt, which comes to the middle of your calf. This is a tricky length, so use our guide to finding the right midi hemline for your height.
