Coco Guaff's IGTV series continues with another video from her time in New York. She begins with behind-the-scenes shots from her visit to the Instagram offices, followed by getting stopped on the street by fans. The 15-year-old then takes viewers on her trip to Glossier, where she meets makeup artist Sir John.

"I don't use a lot of product," Gauff said, adding she has "like three things" in her makeup bag and that highlighter is her favorite. Sir John gives her a few fast tips for her daily routine, and, in turn, she gifts him a New Balance "Call Me Coco" shirt. 

"I really like the way I look right now," Gauff said before wrapping up the second of her four IGTV videos by heading to practice inside Arthur Ashe Stadium.

Gauff recently cracked the Top 100 for the first time after winning the WTA title in Linz. She's all the way up to No. 69.
