Creating comfort-first underwear for every woman
For years, Adelfi brand founder Christina Ly was frustrated with how little thought went into underwear — especially where it mattered most: the gusset. Everything she tried was too narrow, too flimsy, too much of an afterthought.
She stopped settling and started working on the solution. She studied the process, the materials, the why behind it all. What began as one woman's pursuit of better underwear grew into a brand built by women at every step. From the product itself to the packaging, imagery, and creative vision, female voices helped shape every detail. The result? A pair you would reach for every single day.
Adelfi isn’t just about better underwear. It's about raising the bar for what women deserve.

RESEARCH
Vagina Diaries: NYC Market Research
What does a bright pink vulva suit, NYC's Washington Square Park, and underwear have in common? Our founder, Christina!
She asked women one simple question: “How well does your underwear actually fit?”
The answer? "It doesn’t."
Through days of measuring crotches and gathering stories, she had found the problem— and the women who needed the solution.
SOURCING
Heading Abroad
Determined to do things differently, Christina traveled abroad to meet directly with manufacturers who share her commitment to quality, transparency, and ethical business practices.
Because knowing how it's made is part of making it right.
TESTING
Creating the Comfort
Before launch, Adelfi went through multiple rounds of wear testing: from gusset width to elastic thickness, every adjustment came straight from lived experience.
Comfort isn’t something we guess: it’s something we prove.
