We had a training day today with staff only and were asked to dress for walking so I went in my yoga leggings and sneakers. It wasn't a walk (well it wasn't my idea of a walk.....more like a stroll). I changed into jeans and boots when I got back and a colleague said "oh you've had a change of clothes." I said "I"m not staying in my yoga pants all day." He laughed at me as if I was a bit weird. Before I would have felt comfortable in my yoga pants all day, but I don't even like to go into shops in my exercise gear these days. How do other people feel about it? I am someone who is definitely on team casual too.
