In case you managed to avoid the internet for the entire week, on Thursday night, Kylie Jenner celebrated her 21st birthday with a pink-hued, celebrity-filled bash to ring in the big occasion. And what better way to celebrate a milestone than with a brand new hair color? Following in big sister Kim Kardashian‘s shoes, Jenner arrived at the party with a butt-grazing blonde ponytail, a far cry from her signature black bob. Also trying out something new this week was Lucy Hale, who debuted what she dubbed a “rorange” shade of eyeshadow, which just means an alluring mix of red and orange. Meanwhile, top models like Lily Aldridge and Ashley Graham took advantage of the last few weeks of summer with some beach-ready, natural looks. Here, a look at the best beauty moments of the week on Instagram.
