Heidi Klum’s shorts are just too short here – when trying to decide how long you should wear them, the rule is to never put a horiztonal line on your widest point – and as you can see, these shorts end right at the widest part of Heidi’s thighs. A couple of inches longer and she could have carried them off better, but this draws attention and it’s not flattering.
Killer Heels 
I like my shorts around the knee now, it’s a great option to a skirt, and great for active moms who must bend and move around a lot! I like to wear them with ballet flats or a low heel. Easy to wear!
Shorts to just above or around the knee in a slim cut tend to be more flattering for most women’s legs (especially when we’re over the age of 16).
