SXSW 2013 fashion isn't just about looking trendy. It's about the utilitarian purpose and promotional accessorizing, like those still-ubiquitous rubber bracelets (like the yellow Livestrong ones) that display the causes you support.

This tattooed arm (arguably an accessory itself) is wearing a few black rubber charity bangles. His 'Nice Kicks' shirt is also promotional. In this case, fashion is a byproduct of promotion.

Shirts and bracelets are perfect places to promote things you like and care about, especially when there are as many impressionable eyeballs as there are in Austin.
