Can thoroughly recommend two tailors from a recent visit. Both had excellent service and the end product is of really good quality. Both meticulous over alterations and both shipped our orders back to the UK for us (at the same cost as the Post Office). Packages arrived safely.
Sun Tailors, 273 Nguyễn Duy Hiệu - 2 minutes walk from the Life Heritage Resort. http://www.suntailors.com. This is a family run business and very friendly service. Nothing was too much trouble.
BeBe Tailors - 11 - 13 Hoang Dieu str - ask for Lou.
Both of these tailors make everything from scratch. Perfect fit and very happy with the end product. Definitely have no hestitation using them again or recommending them to anyone else.
