This week is all about floral minis, statement heels and sexy side cut-outs—so all things good for spring, basically. Read on to see who topped our leaderboard in chic!

Taylor Swift stole the sartorial show (even after skipping the red carpet!) at the 2015 ACM Awards in Arlington, Texas on April 19: The star donned a sky blue Reem Acra column gown featuring a thigh-high slit and peek-a-boo side cut-outs. In New York that same night, January Jones looked white-hot in a Prabal Gurung onesie with sheer illusion panels at the Good Kill Tribeca Film Festival premiere.

Sarah Hyland wowed at the Los Angeles premiere of See You In Valhalla on April 22 wearing a decidedly un-vikinglike Oscar de la Renta frock with intricate floral detailing. She finished her look with lace-trimmed black pumps, making for the perfect monochromatic red carpet get-up.

Two-peat alert: Rose Byrne garners a spot on our list for the second week in a row for this blue flower-embellished Preen number, which she wore to CinemaCon 2015 in Las Vegas on April 23.

Emmy Rossum, meanwhile, took to Variety's Power of Women luncheon earlier today in a tiered orange mini by Oscar de la Renta. We were most taken with her matching pumps, which offset the summery get-up quite nicely.

Blake Lively, Best Loks of the Week

And one for the road: Blake Lively had so many chic looks this week that we had to file her in a category all her own. From her structured Ralph & Russo frock, to the printed halter midi from Lindsey Thornburg, red Marchesa stunner-of-a-gown, koi-printed John Galliano frock and that plunging Zuhair Murad number, we couldn't get enough of Blake (and Blake couldn't get enough wardrobe changes).
