This tailor is different from all the other shops you find in Hoi An. You'll find high quality craftsmanship, competent and experienced staff, and appropriate prices at Yaly. You're not pressured, rushed or talked into accepting mediocre results like in other shops. The variety of options is overwhelming, but you're assisted with patience and skill through the selection and fitting process.
If you want a quick and as cheap and possible standard solution, you can go literally anywhere in Hoi An. If you want to be sure, you'll be satisfied with your new clothes, you can rely on Yaly.
And while other stores give discounts for 5 star ratings, Yaly doesn't have to play this game. This is an honest review after my super pleasant experience here.
