Shop for shirts by bra-size

The only shirts to be sold by bra size, the InStyle Essentials "Perfect White Shirt Collection" is available in 30 sizes ranging from 32B – 40H, providing a great fit for women of all proportions and shapes, whether large or small-busted. The collection launches with three styles: classic button-front, weekend tunic, and the bow blouse.

InStyle editors worked closely with TrioFit co-founders Rebecca Matchett and Drew Paluba to develop the versatile styles. The collection launches in InStyle's September issue, the largest issue in the brand's 19-year history. Matchett and Paluba developed TrioFit's proprietary technology in 2004, a sizing system that takes into account a woman's bust and band size, rather than dress size.

"Men have had access to individualized shirt sizing by arm length and neck size for generations.  We felt it was time for women to have equal access to great fit," says Rebecca Matchett, CEO of TrioFit.  "And we all know that properly fitting clothes boosts women's confidence, and helps them look and feel their best."

"So many women write to us at InStyle about their struggle to find well-fitting clothing that we were compelled to find a solution.  Given that the white shirt is both a wardrobe staple and notoriously tough to fit, we decided to start with this collection of great-looking basics," says InStyle Editor Ariel Foxman. "The collection solves a common fit problem associated with button-front shirts: They often fit through the torso, but pull across the bust.  Our solution is an affordable, 'nearly custom' wardrobe staple.
