There are no strict rules about what should be included in a bridesmaid proposal, but some trends have formed over the past few years. First, be sure to include a personal note with a short but sweet message for your loved one. Then, you get to have fun selecting your bridesmaids' gifts. Some common bridesmaid proposal gifts include items like sweets and treats, a pair of soft silky pajamas or a robe, a bottle of champagne, personalized jewelry, nail polish, bath bombs, candles, and fluffy slippers. If it's thoughtful, cute, or cozy, it will make a great addition to your bridesmaid proposal box.
