Old Navy $0.99 flip flops are only ok if you are in a swimsuit. Basically heading to, from and around a beach, pool or lake. Or in a gross public shower. No other exceptions. We don't want to see these in the workplace or at the mall. Grow up and put on real shoes.
Ankle-strap sandals. Only if you don't have "cankles." Trust me. These are beautiful but they will make your cankles look like sausages.
Anything other than the "Sometimes" or "Never"s with a nice pedicure. You don't even have to pay for one. As long as you are clean and patient, you can give yourself a killer pedicure.
The slingback wedge. When in doubt, put on a slingback wedge. They are my favorite. Leg-elongating, comfortable and effortlessly chic. Get a pair in a fun color and throw them on with anything. I CANNOT WAIT TO BUY SOME TOMS WEDGES.
Are you Bear Grylls? No? Ok then. These should never be worn around humans.
