Fresh off of their CFDA Awards win for Womenswear Designer of the Year, the twin sisters behind The Row, Ashley and Mary-Kate Olsen, hit another milestone on Saturday: their 29th birthday. With some of their dearest friends in tow, the Olsens headed to the Hamptons where they threw themselves a party of Olympic proportions — well, at least it was Olympic in theme — that included competitive track and field games, a dunk tank and fireworks. The ladies even had America-themed t-shirts made for each team, allowing guests to proudly declare their allegiance to a single sister for the day.
Read on for scenes from the Olsens' birthday bash from Instagram, and for the record, Team Ashley won.
