YOUR NEXT POP-UP

Tailored modern classic apparel for sophisticated women.

Created with awareness for functionality by active humans who value timeless longevity. Carefully curated fabrics sourced sustainably from textile stalwarts like Japan and Italian, and thoughtfully produced primarily by women-owned sew houses in NYC and local seamstresses in Colorado.

Founded by sisters Jillian Glenn Altman and Hillary Glenn Riley, GLENN + GLENN launched quietly in 2019 with a capsule collection of warm weather essentials. Combining our love for art, architecture, fashion, photography and all things sustainable, we tested our skill sets in apparel design and entrepreneurship to create a ready-to-wear fashion brand that promotes slow-fashion, small batch production and awareness for curating one’s wardrobe.

Having worked in the fashion industry for over a decade, Hillary launched her career at Diane von Furstenberg in New York City and subsequently transitioned into knitwear design. She returned to Colorado to design for major players in the lifestyle and performance industry.

Jillian’s background as a contract designer in corporate branding, art direction and photography has kept her close to the entrepreneurship atmosphere. After designing, branding, merchandising and photographing for dozens of other clients and apparel brands, it was time to act on the idea they had shared since childhood. Hillary and Jillian began building Glenn + Glenn in 2017.
