" I think a marvelous stunt would be to have your best friend (or the most critical acquaintance) take some candid color snapshots of you from all angles, dressed just as you usually appear at, say, six in the evening. The same hairdo, the same makeup, and if possible the same expression on your face. Be honest! Be sure to have her take the rear views, too.
There ought to be some other shots of you wearing your best going-out-to-dinner dress, or your favorite bridge-with-the-girls costume — hat, gloves, bag, and costume jewelry. Everything. Then have that roll of film developed and BLOWN UP. You can’t see much in a tiny snapshot. An eight-by-ten will show you the works — and you probably won’t be very happy with it. Sit down and take a long look at that strange woman.
Is she today’s with-it person — elegant, poised, groomed, glowing with health? Or is she a plump copy of Miss 1950? Is she sleek, or bumpy in the wrong places? How is her posture? Does she look better from the front than from the back? Does she stand gracefully? […] Feet together or one slightly in front of the other, is the most graceful stance.

I always pin my bad notices on my mirror. How about keeping those eight-by-ten candid shots around your dressing room for a while as you dress? "
