Getting tailored clothes is a recommended Shanghai experience, as it will cost so much less than at home and the artisans are skilled (provided you’re clear about exactly what you’re after) and quick. At the textile market in the Old City, near Liushui Lu at 399 Lujiabang Lu (南外滩轻纺面料市场, nánwàitān qīngfǎng miànliào shìchǎng; daily 10am–7pm), on-site tailors will make you a suit for around ¥500, including material (you’ll have to barter a bit), which will take a couple of days; a shirt should be around ¥150. It’s all a bit hit and miss, but Jennifer at Unit 237, Andy at 295 and Xia at 326 are all considered a good bet.
If you’re looking for a more sedate experience, or a tailored qipao, your best bet is to head to one of the dozen or so specialist tailors on Maoming Nan Lu, just south of Huaihai Lu. Three shirts in one of these stores should come to around ¥800, a suit will be around twice that.
