Brand profile
American menswear label built on button-down shirts cut with shorter hems to be worn untucked, now spanning knits, chinos and womenswear.
24 brands like Untuckit like Mizzen+Main, Ministry of Supply, Charles Tyrwhitt →

The core product is a button-down cut with a shorter, curved hem and trimmer body so it reads as intentional when worn untucked, rather than a tucked shirt left loose.
Physical retail drives the business: about 80 stores by early 2024 plus 14 more that year across the US, Canada and UK, with locations chosen using sales and site data.
Since 2011 the line has expanded into polos, knits, chinos, outerwear, performance fabrics and womenswear, with recent work on digitally bonded garments using Supima cotton.

UNTUCKit was founded in 2011 in New York by Chris Riccobono, who developed a button-down shirt with a shorter, curved hem and trimmer body engineered to look deliberate when worn untucked; co-founder Aaron Sanandres serves as CEO. The line has widened to polos, knits, chinos, outerwear, performance fabrics and womenswear. Retail is central: roughly 80 stores were operating by early 2024, with 14 more opened that year in US, Canadian and UK markets and further openings planned, using data-driven site selection. Recent work includes a Supima and CreateMe project on digitally bonded garments.
