Sastrería - Zihua T shirts...

I don't know if this has changed, but we found a shop on Ejido called Inbursa which sells (sold?) high quality T shirts and a good selection with only Zihuatanejo printed on them.

The store is located on the north side of Ejido just before you get to Los Braseros from Benito Juarez.

They also have a satellite location in the Mercado but trying to describe where to find it is a challenge

Hope they're still in business because it is our "go to location" for T shirts.

Roberto!

That sounds like the shop that makes t-shirts on the spot, with hundreds of different choices of appliques, but I never saw just "Zihua".
(I've often thought, just to irritate Zihua regulars, I'll get one that says "Zihuat"
I'd also like to get one with big reproductions, front and back, of that Eagle-head "Hecho en Mexico" logo. I bought one off-the-shelf in Zihua a few years ago, but the only one I could find unfortunately said "Hecho en Mexico, Pero Bien Hecho", which someone, sadly, apparently thought was funny.
