We are in love with Irina Shabayeva’s design asthetic on this season of Project Runway. And because she is the winner of last week’s “Fashion Headliners” challenge, we want her Pop in the City Dress more than ever.

Luckily, this week’s 20% off discount on her entire collection at ProjectRunway.com makes it all the more possible. If you share in our Irina obsession, you can just use code “WINNER” at checkout to redeem this fabulous limited time offer. It’s a bold city piece that we recommend accessorizing with sky-high platform heels and a belt!

In last night’s avant-garde and beachwear challenge, the designers definitely had their work cut out for them. Not only were they asked to partner up with another designer, but they also had to create two (yes, two) runway pieces!

Some teams made it work (brilliantly!) and others all but had a high fashion meltdown. Which team do you think pulled it off best?
