Hello, I don't know if any of these stores are in Guadalajara (available in Mexico City) but if you are looking for high end, here you go:
Moda in Casa
Roche Bobois
Casa Palacio (not to be mistaken with Palacio de Hierro)
This ones are not as high end but still good to go:
Crate and Barrel Mexico
West Elm Mexico
Pottery Barn México
I've also heard about a store in Guadalajara, but I haven't been:
