Your bridesmaid and groomsmen gifts should be a thoughtful token of appreciation for their time, effort, and support. But should you and your fiancé spend the same amount on presents?

Should my fiancé spend the same amount of money on groomsmen gifts that I spend on bridesmaid gifts?

Truthfully, the best gift you can give your wedding party is a pleasant, drama-free experience as they help you prep for the big day. However, it's also important to thank your attendants with a tangible gift to show your appreciation. While every couple's situation (i.e., wedding budget, number of bridesmaids and groomsmen) is different, you'll want to sit down with your fiancé and have a discussion about thank-you presents. One idea is to jointly decide on an appropriate price range per gift, then choose presents accordingly. But if, for example, you decide to give your attendants $80 necklaces while your fiancé gifts his groomsmen with $150 custom Nike sneakers, that's totally fine, as long as you've communicated about this. Whatever you decide to buy, just be sure to consider what you've been asking financially of your bridesmaids and groomsmen. If they're dropping a ton of cash on wedding-related things like an airplane ticket, hotel room, and $500 bridesmaid dress (not to mention the bridal shower, bridal-shower gift, and wedding present), then a $20 necklace from Etsy might seem a little ungracious. You're certainly not required to buy something that equals how much they've spent, but the amount should convey a sincere gratitude for how much time, effort, and money they have put into your wedding. As a rule of thumb, something between $75 and $150 should suffice.

The rehearsal dinner is a great opportunity to present these gifts to the wedding party (especially if the gifts are items you'd like them to wear to the wedding) and acknowledge their support and help in front of your close friends and family. Other couples decide to distribute gifts the morning-of the wedding, as everyone is getting ready. Regardless of where you present your gifts, just make sure to convey how grateful you are for your attendants and how you couldn't have made it to the altar without them.
