Custom Intimate Apparel Manufacturer — OEM/ODM Heritage Since 2015
We’re the OEM/ODM partner brands choose when they refuse to compromise on three things: PFAS-free chemistry, AQL 2.5 quality discipline, and 7-day sampling speed.
A letter from our founder
“We don't manufacture underwear. We manufacture dignity — one stitch at a time.”
Since 2015, my mother handed me her stained nightgown and asked me a question I couldn't answer: Why are women still choosing between a good night's sleep and their dignity?
That question built LJUNDERWEAR.
We started as a six-person workshop in Gurao, obsessed with one problem: how to make a period-proof gusset that's truly leak-proof, breathable, and free of "forever chemicals".
Today, we ship to 28 countries. But the standard hasn't changed: every sample still passes my desk before it ever leaves the building.

Behind the brand
The team behind LJUNDERWEAR
Our core bench has worked together for more than ten years. These are the department heads who set the bar for quality, production, and sampling every day — plus the crew on the floor beside them. Same faces. Same standards. No script.
Liao Lihua
Quality control
Defects caught early cost less than recalls.
Runs incoming, in-line, and pre-shipment discipline — translating years of inspection notes into standards your SKUs meet before they ship.
Huang Lanmeng
Production
The line only moves as fast as skill allows.
Started on the sewing line over a decade ago; now aligns staffing, cadence, and realistic throughput so bulk stays true to the sealed sample.
