I've made a few suits and shirts from Dream Bespoke - generally high quality, with suits starting at around 6k+, while shirts are 500+.
Shirts I have no complaints about; for suits, their fitting is more "classic" and generally "looser" than I would like, hence if you like the more modern slim fit, you may have to emphasize that more.
Generally, if it fits your budget, Dream is considered the best in its class (e.g.tier 2, below tier 1 WW Chan) by HK locals.
