What might be confusing is that there are sort of two tailor shops in Hyrule Town. The one in old town is where Link goes to get his nice clothes, where he picks up the bracers. I did forget to mark that one on the map, my bad. It is in the central square, across from the cafe, just southwest of the Postage and Trading company.
The second tailor shop is the cobbler/tailor shop, in the slums. It's run by Bob and Ester, and you did start designing that one. However, we thought that design could be improved, I don't remember but I think some of the comments were that it looked too big and nice for a struggling business in the slums (like, maybe Bob should have one shelf of shoes, not five, maybe Ester should be selling fewer clothes and not have so many mannequins, maybe a less opulent carpet, perhaps a smaller store, etc.
So yeah, the tailor shop is done, but the cobbler/tailor for the slums still needs a little work.
