This is a question we get asked quite a bit. Monogrammed Bridesmaid Shirts are definitely considered a gift from the bride, meant to be worn at the venue, or wherever the bridesmaids and bride are getting ready for the ceremony. They look great in the wedding photographs and are meant to keep makeup and hair from getting messed up. These things are important for a beautiful wedding and are part of the entire experience, so the bride should be the one paying for this expense. This is part of the gift she is giving her bridesmaids. The shirts are mainly for the bride, so she'll have great memories of 'getting ready' with those closest to her on her special day.
We do, however, recommend adding a small gift that can be used separate and away from the wedding festivities.  An appropriate gift can be anything from a small piece of jewelry with a nice meal at a fancy restaurant, to a small token like a tumbler with her name on it, or customized tote, depending on your budget.
Don’t break the bank, but if you are having a grand wedding, please don’t skimp.
Your wedding party is having to put a lot of money towards your big day (travel, taking time off for work, paying for her dress) and this is part of her “thank you” gift.
Make sure your gifts are thoughtful, letting them know you took the time to get them something they will appreciate and not just something that helped your wedding look pretty.
Bridesmaid Button-ups are ideal for that gorgeous look at the venue, and your photographer will love you for having them, but don't forget it shouldn't be the only gift.

PS: Remember to steam the fold lines and wrinkles from the shirts. Your photographer will thank you!
