1. As her honorable "maid," you're expected to give the bride your full attention on the day of the wedding and be ready to help with anything that may come up.

2. Don't just ask, "How can I help?" Anticipate any needs the bride may have. If you know, for example, that the only way to calm her nerves is with a bag of peanut M&M's, be prepared to make a junk food run on the morning of the wedding.

3. Assign a bridesmaid or two to take care of greeting the DJ and accepting flower deliveries.

4. Make sure you're among the first guests at the ceremony and double check that all the bridesmaids have the correct bouquets.

5. Make sure the bride looks good. Show up at the bride's house several hours before the wedding to help her get prettied up. Throughout the day, help her adjust her veil, fix her hair when it falls down, and apply more make-up if she needs it. Be prepared to go through this process several times-the bride wants to look her best on her wedding day, and if she hasn't hired a professional hair stylist or make-up artist to be with her every step of the way, you're the next best thing. Encourage the bride and tell her sincerely that she looks beautiful at all times.

6. Before she walks down the aisle, bustle her train and make sure she's comfortable walking with several feet on her dress trailing behind her.

7. During the ceremony, hold the groom's ring, which will probably be presented to you on a velvet pillow by an adorable little ringbearer. Most maid of honor dresses aren't equipped with pockets, so make sure to place the ring on your thumb or index finger for safe keeping until you pass it over to the bride.

8. While the couple is exchanging vows, grab the bride's bouquet and return it to her before she walks back down the aisle.

9. The bride might ask you and the best man to sign the marriage license, so be prepared to hand off your bouquet to a bridesmaid when you are ready to sign.

10. If you are attending a Jewish wedding, the bride might ask that you save the glass shards left on the floor when the groom breaks a glass with his foot. If this is the case, be sure to have a cloth napkin on hand so you don't get cut.
