Sandals shown are from Indian Summers in Summerland, California
(These are for women and are not the ones my husband finally purchased for himself!)
Think about the way you try on shoes: You may have your foot measured, you walk around the store in them, sometimes on various surfaces, you envision them with different outfits, and you insist that they look good and feel good before taking them home. Having the same exacting standards will serve you well when you try on clothing. Ask yourself if the clothing feels good on your body. Does it fit just right (or will it after some tailoring)? And will it complement other pieces in your wardrobe? Move around in the clothing, sitting down, stretching, and taking a walk around the store. How do you move in it? Do you have to adjust the clothing, pulling it here or tugging it down there? If so, leave it in the dressing room.
Careful shopping means fewer shopper's regrets. So take your time when you are trying on anything, from shoes to clothing.
