I have to wear a uniform, but they're super comfortable and warm.
Continuing on this, my uniform is usually the casual version, however there are two official uniform days in our 6 day learning week. The casual uniform is either the school's black, white or red polo shirt with the school kilt and leather shoes, and the official uniform is either a long sleeve or short sleeved button-up shirt with a tie matching the school quilt, also with leather shoes. You can wear the school sweater if needed
For rowing you can wear the school's athletic shorts and shirts or the Varsity rowing shirt.
