This week, the party set ascended upon London, where the menswear fashion circuit kicked off with shows by Wales Bonner, Charles Jeffrey, and more. While the up-and-comers were all the buzz on the runway, the heavy hitters maintained their ground by throwing a number of star-studded fetes. Burberry's Christopher Bailey, along with Natalie Massenet and Dylan Jones, hosted a breakfast to kick off the week, where Rosie Huntington-Whiteley's equally attractive younger brother Toby made his mark on the fashion scene. Stella McCartney held a party for her new menswear collection, drawing Steven Tyler, while Rag & Bone feted their new flagship with Stacy Martin. Stateside, Jason Wu and Kate Bosworth co-hosted an intimate dinner for the designer's Grey Jason Wu line, and Hermès had not one, but two very Instagram-friendly soirees, complete with a laundry service to tie-dye all of your extra silk scarves. Here, all the party pictures that you may have missed.
