Hoi An was a trading port for Japanese, Chinese and Dutch merchants, and the old town survived the wars almost untouched — yellow walls, tiled roofs, and silk lanterns strung over every lane. It is also thoroughly, unapologetically touristic. Accept that, get up early or stay out late, and it's still one of the most charming places in Vietnam.
Hundreds of tailors will make a suit, dress or coat in 24 to 48 hours. Quality varies enormously. Allow at least two fittings — the first garment is almost never right — bring a photo or a piece you already like, agree the fabric and the price in writing, and don't leave the final fitting to the morning of your bus. Cheap quotes usually mean polyester blends sold as wool.
Two or three nights. Any less and the tailoring won't be finished; any more and you'll have walked every lane twice. October to November is flood season, when the streets sometimes take to boats.
