7. Pair Sky-High Shoes with Tame Hemlines When going for major air, keep your hemlines at an inch above the knee. But when wearing a short skirt or dress, wear a lower heel or flat — it will balance you out and keep you from showing altogether too much leg.
I'm sure I'm missing some fundamental aspect of fashion, but I'm not sure how a shoe can make you show more or less leg while wearing an already short skirt. I'll accept the fact that high-heeled shoes make the leg appear longer (and more shapely), but I really doubt they can make you show "too much" leg when your skirt is already shorty short.
Besides. If you're wearing a short skirt, I'm going to hazard a guess that the intent is to show off the leg anyway, so why not wear high heels to make them look oustanding?
