Dress Your Age
And we don't mean ancient. Mother of the bride dresses have a tendency to be dowdy, so steer clear of looks that will age you. If your two-piece suit makes you feel late for a country club luncheon or has enough sequins to rival a disco ball, put it back on the hanger. Likewise for hems that hit mid-calf (why did any designer think we wanted to draw attention to the thickest part of the leg?) Instead, opt for a sheath and long coat or a dress with a bolero jacket. Sleeves of any length are more flattering than sleeveless styles. Or use a wrap to cover bare arms. And take it easy on the rhinestones.
Even if you could pull off a sexy look with no problem, it's still probably a good idea to model the dress for your daughter. She'll surely want you to look beautiful, but perhaps a siren red strapless affair wasn't quite what she had in mind for her dream day.
