Some fun tips I've learned from readers and friends over the years:

Downplay jowls with gorgeous earrings, but stay away from chokers, which bring eyes straight to your jawline. Love necklaces? They should hit at the collarbone or lower. Don't wear elaborate earrings and a necklace, pick one or the other. Both can be overkill.
Got a crepe-y neck? Cuts that hit just below the chin will draw attention away from your neck. Long cuts attract the eye downward, according to stylist John Barrett in the November issue of O magazine. I also love the look of scarves, wrapped several times around the neck. Very European.
Downplay wrinkles by highlighting your eyes. Great eye makeup will make eyes "pop" and attract eyes away from the wrinkles on your face. Keep brows groomed and filled in.
Laugh lines around lips? Plump up lips and bring attention to THEM, not the surrounding area with a moisturizing lip gloss. Any time you add moisturizer to skin or lips, it plumps them up, making them appear more youthful.
