A Before-and-After Look at Taylor Swift's Drastic Style Transformation

Before: Believe it or not, Swift never failed to look impeccably polished every time she stepped out, ran an errand, or left the gym. Her style identifiers: Fitted pieces, ladylike extras, and pumps. Always pumps.

After: A casual, devil-may-care outfit, featuring a flannel shirt (with the sleeves haphazardly scrunched up) opened to reveal a basic white tee, destroyed skinnies, and white sneaks. 

Before: Crop top (and/or coordinated separates) + top-handle purse + Mary Jane heels = Swift's date-night uniform.

After: A super chic, grown-up date-night look. She styled her caped LBD with a Louis Vuitton trunk clutch and patent black pumps. 

Before: Never one to miss an opportunity to bare her midriff, Swift styled a black-and-white crop top with a sweet pleated skirt, a heart Roger Vivier purse, and peep-toe pumps.

After: Nothing sweet about this. For Gigi Hadid's birthday, Swift glittered in an edgy one-shoulder asymmetric number embroidered with rainbow-y sequins. The finishing touches? A vampy lip and chunky midi boots for an extra dose of edge.

Before: At the 2016 Grammy Awards, Swift did girly-glam with a Versace design that boasted a bright orange bandeau and a fuchsia ball gown skirt. 

After: Granted, the 2016 Met Gala had a theme—"Manus x Machina: Fashion in an Age of Technology"—but that didn't lessen the shock. Swift wore a silver python Louis Vuitton number with bondage-like lace-up sandals and only one visible earring (and ear cuff). Style transformation, complete.

Before: A crop top and high-waist hot shorts were among Swift's summertime go-tos. And check out that heel. 

After: No high-waist retro styles here. Swift tucked in a simple black tee into a teeny pair of gray denim cut-offs, with white sneakers. Sneakers!

Before: A simple, chic navy jumpsuit that Swift elevated with her usual ladylike extras.

After: Swift tapped her inner badass in a racy sheer black lace jumpsuit with combat-like boots (that's right, no Mary Janes or top-handle purses in sight).

Before: Crop top. Need we say more?

After: Swift switched things up when she styled her black skinnies with a white tee, a gold choker, and sandals with edgy buckled straps.

Before: Swift channeled a preppy schoolgirl with a cropped navy knit, a plaid asymmetric skirt, and tasseled brogues.

After: The star brought her love of the asymmetric silhouette to the other side, but styled it with her new go-tos: a simple black tee and chunky midi boots.

Before: A graphic, checked print got the retro-glam treatment as a pair of high-waist shorts styled with a black tank, cat-eye frames, and aqua pumps.

After: Cool-girl grunge, through and through. She toughened up a checked dress with a coated leather jacket, a box Mark Cross clutch, and combat boots.

Before: We spy transitional style pieces—the bomber tied around the waist and her chunky cut-out platforms—but the star styled her black mini with a darling letter-scattered tee and a black croc ladylike bag.

After: An oversize tee, anklets (on both ankles!), and Chuck Taylor slip-ons had us doing a double-take.
