As expenses mount, bridesmaid contemplates dropping out

DEAR HARRIETTE: What do you do if you’re a bridesmaid, but the wedding expenses are mounting? This is my best friend’s wedding, and I’d hate to miss out, but some of these things are too demanding: engagement party, bridal shower, bachelorette party, dress, hair, makeup, alterations and more. The list of events and expenses just keeps growing. Should I bring this up to the bride, or politely bow out?
