Should I wear 3-inch strappy sandals or open-toe slingback style shoes? 
I am wearing a long, fitted, one shoulder, champagne color dress for my son’s wedding in March. The strappy sandals are gold leather and the open-toe slingback style shoes are nude color.

My choice would be nude color open-toe slingback style shoes with your long champagne color Mother of the Groom dress. You will be on your feet for long periods of time so 3″ strappy sandals might be uncomfortable. Also, gold shoes will draw attention to your feet. Nude color shoes will blend in with the champagne color of your beautiful, long, fitted, one-shoulder dress. The focus of attention should be on your face with an up-to-date hairstyle, flattering makeup, and a pair of beautiful earrings. With a one-shoulder dress, earrings should be enough jewelry. If you wear gold earrings you can carry a gold sequin or leather clutch. If you are wearing sparkly (quality rhinestone or diamond) earrings you can carry a nude color or silver bag. If you wear pearl jewelry you can go for a nude color, silver, or gold color clutch. Earrings in combinations of gold and sparkly or pearl and sparkly are other options. Go shopping for a stylish clutch that works with the jewelry you plan to wear.

What Should the Mother of the Groom Wear?
You are the Mother of the Groom. You want to look great and make a good impression at your son’s wedding. How do you begin to choose an outfit? It is a good idea to talk to the bride about her color scheme for the wedding and find out what type of wedding she is planning (daytime or evening).

What style purse & shoes would be best with a lace dress?
A lace dress is perfect for a Mother of the bride. Closed toe pumps or closed toe slingback style shoes would be very stylish with your dress. The heels should be no higher than 2 1/2 – 3 inches high. With closed toe shoes you can wear ultra, ultra, sheer hosiery for a more polished look. Weddings are dressy and stockings look great at special events. A clutch style or small size purse would be appropriate for the Mother of the Bride.
