An old-school tailor in Khlong Tan known for proper construction: half-canvas jackets with soft shoulders, hand-rolled lapels and no fused interlining.
The Primary Haus is a small tailor tucked away on Soi Naphasap in the Khlong Tan area, off Sukhumvit. From the outside it feels more like a neighbourhood café than a tailor, with outdoor seating under the trees.
Inside, the focus is on proper construction. Its made-to-measure suits use true half-canvas with zero fusible interlining, unpadded shoulders and hand-rolled lapels — details that set it apart from the glued, mass-produced suits sold at many tourist shops.
It is one of the few places in the city still using traditional cutting techniques, and it works by appointment, with personal consultations and close attention to detail.
Well-built suits with real handwork.
What makes a Primary Haus jacket different from a cheap suit.
A layer of canvas is sewn into the chest instead of glued. It shapes to your body over time and won’t bubble after dry cleaning.
Soft, natural shoulders follow your own shape for a relaxed, modern look that suits Bangkok’s climate.
Lapels are shaped by hand so they roll softly rather than lying flat and stiff.
The Primary Haus does not publish prices. Expect to pay more than at fused-suit shops, reflecting the half-canvas construction and handwork. Ask for a written quote at your consultation. [verify]

The Primary Haus is the pick for buyers who care about how a suit is built. True half-canvas, soft shoulders and hand-rolled lapels at a relaxed neighbourhood shop make it a strong choice for weddings or a suit meant to last. Book ahead and allow time for the handwork.
