Taylor Swift, lover of all things prim and twee, had a massive style overhaul this summer when she ditched her typically covered-up looks for some ab-baring crop tops, form-fitting skirts, and teeny-tiny shorts. For everyone who'd grown accustomed to her adorable cardigan-and-sundress combos, this was a different, but welcome, change. Girl's got legs FO DAYZ. Tay Tay continued her f-AB-ulous reign of ~flawless~ style at this year's iHeartRadio Music Festival in Las Vegas when she strutted on stage in a glittering, long-sleeved, cotton-candy pink crop top and matching skirt that perfectly showed off all the hard work she's been putting in at the gym.

If an ice dancer and a fashion blogger had a baby, this look would be the result. The girly-glam outfit was a perfect mix of Old Taylor's style (super-duper sparkly) and New Taylor's style (less super-duper sparkly, more plain ol' fierce), and it matched the totally fun vibe of her "Shake It Off" performance. This was also a big change from her past performance ensembles, which weren't nearly as daring.

Don't believe me? Check out what she wore just a few short years ago during her "Speak Now" world tour in 2011:

Cute? Obvz. Ab-tacular? Not so much.

Even her 2012 performance at the iHeartRadio Music Festival showed her looking like a pop princess rather than a fashion kween:

Of all the styles she's tried out, "1989” definitely looks the best on her, IMHO. Keep it up, Taylor, 'cause even though we're getting drool all over our keyboards thanks to your jaw-dropping outfits, and crying on the inside because we know we'll never be able to ransack your closet, you're KILLIN' it.
