Tailors
I’ve had good experiences with YinYin Fashion Alteration Specialist in the past. They’re located at Tanjong Pagar. I had three pairs of pants altered there. Turnaround time is quick and the quality of the alteration is good. Now that I no longer work at Tanjong Pagar, it’s a bit inconvenient to go down to tailor clothes.
I’ve also had a couple t-shirts tailored at Xin En Tailoring in Tampines. It was just a simple hem on both shirts, so I can’t speak for their quality on more complex tailoring jobs. The shirts turned out well though. A part of the stitching on one shirt was a bit uneven, but they’re just t-shirts, so it’s not a big deal at all. Turnaround time was a week.
