Glasgow-Shopping-50s-streetart… fashion-tips?

Hi. We´re planning a trip to Glasgow this summer and we are looking for some shopping tips as well as tips for what to do/see of the beaten Glasgow path. We simply love 50s and 60s merch such as bags, interior etc. We are also into graffiti, street art and british street-culture, but we are open for any good suggestions for where to shop and what to see and do in Glasgow that are not fronted in the typical tourist brochures. Kind regards from Norway
