As any good bridesmaid knows, it's not about you—it's about the bride. And yes, this goes even for celebrities. While they're typically in the spotlight, these women took to the sides of their favorite brides to help celebrate their big days, matching dresses and all. Take a look at these star bridesmaids in one of their most special roles.

The actress wore a bell-sleeved mini-dress for her friend's wedding, captioning the photo she posted to Instagram with a simple: "Bridesmaids." If only all bridesmaids dresses could be so on-trend.

Congratulations @britmaack and Ben!"

Dunham and fellow bridesmaids wore possibly the best skirt ever from J.Crew at the wedding for Dunham's childhood friend, Audrey Gelman.
