I wouldn't be caught dead going to class or grocery store in slippers and pjs.
My basic uniform is shades of black and white shirts and black jeans in fall and winter with spiked or rhinestone leather bracelets and the occasional splash of hot pink or red added to my outfits.
I see it all of the times since there is an university nearby and a college campus too as well. So thousands and thousands of students reside in the city.
