Tassel loafers are more mainstream than spectators or weaved shoes. They are very popular with NE trad/ivy, and commonly seen throughout Europe. Having said that, someone in the Northeast may raise an eyebrow towards then while they are non issue in the south, and in fact quite common. I saw a gentleman in his 60s at an evening function wearing bit loafers, a linen tan with navy windowpane and an orange tie. This is classic southern.
