Interesting - I was just thinking that it would be useful to have something about favourite Santiago clothes shops in the "resources" section of the forum. Many of us want to buy new clothes or shoes in Santiago, either to take home as special souvenirs - especially stuff made in Spain. A bonus for me is that Europe's new fashion is 6 months ahead of us because of the seasonal difference. Other reasons for buying are because we are going on somewhere else and want clothes other than hiking stuff, or because we are simply sick of everything after a month or so of wearing the same things!
As Cancelas seems to be mostly the chain stores, with stuff I can buy anywhere. Not very exciting.
Last time in Santiago I gifted myself from small boutique shops in the old town with new colourful patterned jeans, a simply lovely new top, and new shoes. All within the space of a few hours, and all made in Spain! Currently in constant use at home.
