InStyle Summer Soiree: 10th Anniversary

Wednesday night, InStyle hosted its tenth annual "Summer Soiree" at the London hotel in West Hollywood. Some guests were new to the bash but most have been previous attendees over the years.

Twitter was the place to talk about the nights festivities, even for party-goers. Glee's Lea Michele tweeted, “Had so much fun at the InStyle party tonight! Saw my girl @KChenoweth!!”

InStyle kept followers in the fashion loop with tweets such as, "Diane Kruger suited up for the annual @InStyle Summer Soiree in a menswear-inspired Jason Wu ensemble." However, Kruger's androgynous outfit has already got us wondering whether or not it worked.
