We love it when the fashion world infiltrates other areas of our lives, namely television. Who could forget Victoria Beckham's cameo in Ugly Betty (seriously WHO could forget?), Alexa Chung in Gossip Girl, Rachel Zoe in Gossip Girl, Vera Wang in Gossip Girl - hey we're sensing a pattern here. We knew there must be a reason why we missed GG so much besides the image of Chuck Bass in a onesie.
Now since it first aired in 2012 Girls has certainly been good for a star turn or two. Irish actor Chris O'Dowd - AKA Mr Dawn Porter - played venture capatalist Thomas-John who had a brief yet highly entertaining marriage to Jessa while former SNL cast member and The Lonely Island singer Jorma Taccone somehow managed to make us (and Marnie) swoon as conceptual artist Booth Jonathan.
The most fashion forward appearance so far however, comes from J.Crew's Jenna Lyons, a woman whose distinctive personal style has spawned a thousand trends. While Anna Wintour has her signature bob and shades, Lyons works geek glasses, boyfriend jeans and red lippy like she invented all three and encourages us all to follow suit - see other A-listers discovering specs appeal.
Jenna Lyons in 'Girls' season 3
As with most fash cameos, Lyons does little to dismiss the bitchy stereotype of the industry, but she is not playing a fashion editor or designer. In the latest Girls season 3 trailer (check it out above) the J.Crew president appears to take on the role of Lena Dunham's character's boss in a publishing company and she clearly has little time for Hannah's eccentricities. As the show's protagonist bumbles into a meeting, dumping food onto the table in the process, Lyons delivers the fierce line, "And I see you found the snack room as well..." Ouch!
Other notable revelations from the latest teaser include the fact that Hannah looks like she's on her way to getting a book deal having impressed a publisher - but is all as it seems?
We'll have to wait until January 2014 to find out; for now check out Jenna Lyons' style moments below...
