Ravi Sehgal opened a small fabric shop on Bangkok’s Sukhumvit Road in 1976, at a point when the neighbourhood was filling with US servicemen and European visitors who wanted good fabric but had no way to communicate what they actually needed made. Sehgal spoke English, stepped in to bridge that gap, then spent four years training himself in pattern drafting and construction so he could do the work himself rather than pass it along. That’s not a polished founder-myth written for a website — it’s the kind of unglamorous, self-taught origin that tends to be true precisely because nobody would bother inventing it.

The shop is now run day-to-day by Ravi’s son, Amit, out of the same Sukhumvit Soi 19 shophouse. The standard build is half-canvas — canvas sewn into the chest and lapel so the jacket drapes properly, with full-canvas available if a client wants the more labour-intensive version. Worth being upfront about: half-canvas is a perfectly respectable, common professional standard, but it isn’t the same product as full-canvas, and Ravi Sehgal doesn’t market it as if it were. Bemberg lining and natural horn buttons come as standard rather than upsells. No fused-construction suits are offered at all, which is more than some of the shops down the street can say.

The part that actually separates this shop from most of the competition is the trunk show. Ravi Sehgal Bespoke runs private fitting tours through the USA, Denmark, Germany, Switzerland and England at least twice a year — which means a meaningful slice of its client base has been ordering suits, shirts and trousers for a decade or more without ever visiting Thailand. That’s a genuinely different business model from a Sukhumvit shopfront waiting for tourist foot traffic.
