This one is entirely up to you! Traditionally, the bride will pay for herself and her bridesmaids. However, if you're trying to save a little money, you could ask your bridesmaids to pay for themselves. Just make sure it's known before the day of who is paying for what so you can avoid any potentially awkward situations.
Doing hair and makeup sample days before the wedding to figure out what style you want is always recommended and can be a fun bonding activity for your bridal party! So start looking through hair and makeup artists' portfolios and figure out what style you're going for and get ready to feel fabulous!
