I was brought by a friend to Jojo (stall No.134) 10 years ago, and since then it became my only go-to place for shirts. I wear shirts on a daily basis and I must say their shirts check all my requirements: customized fit and design, simple and clean design but paying attention to the important details, good variety of fabrics and patterns, great correlation price/quality. On top of all that, super friendly staff that always remembers you.
I highly recommend this tailor if you ever need shirts, a suit or a jacket!
Extra tip: since everything can be customized to your taste, I always recommend my friends to study, before going there, what kind of buttons, collar, cuffs, or patterns they like, so they can get a shirt that not only fits their body but as well their unique personality and taste.
