The singer stuck to a strict vintage-inspired swim selection … that is, until her shockingly sexy secret getaway with boyfriend Calvin Harris. How did she get here? We look back

HIGH-WAISTED BRIEFS, 2010

Back in 2010 Taylor was still singing country, still rocking curly hair and forming her iconic swimsuit style: preppy prints in retro designs.

NAUTICAL, 2011

Before she decided she wanted her belly button to “be a mystery,” she exposed it (once!) in ultra-low-cut bottoms that she made look more sweet than sexy.

BLUE POLKA DOTS, 2012

When you’re vacationing on Cape Cod with Conor Kennedy (yes, her then-beau from that famous family) we suspect the unspoken rule is “go preppy or go home.”

RED POLKA DOTS, 2012

And Taylor was not going to go home. (Seriously: She bought a house there.)

FLORALS, 2013

Signature stripes to celebrate the stars and stripes? (She’s at a Fourth of July bash.) Too easy. Taylor does red, white and blue her own way!

STRIPES, 2013

Not even water sport participation (seen here paddle boarding with Ed Sheeran) could deter her preppy vibe.

PASTEL STRIPES, 2015

The Internet freaked out when she finally bared her belly button, but we were way more shocked that she ditched the red and blue suits for something so colorful.

DOTTED MAILLOT, 2015

But… it didn’t last long. On the same trip with the Haim sisters, she reverted to her signature full-coverage navy one-piece — but she was in on the joke, writing on Instagram, “She’s always wearing, like, a 1950s bathing suit.”

ITTY-BITTY BLACK BIKINI, 2015

This was close to the period when she welcomed New York into her wardrobe (and bikini selection!).

CHECKED PRINT, 2015

Epic Fourth of July bash? Check. Perfect jummping pic with your squad? Check. Adorable swimsuit? Check.

BLACK LACE, 2016

Sheer lace? Skimpy ties? pose? What did Calvin Harris do to our oh-so-demure Tay?

SPORTY NEON, 2016
