I don’t like to sleep naked. I don’t feel comfortable in my own skin and prefer to layer it with as much soft cotton as possible. But I don’t want to pay $ 25 for sweat pants I’m just using as sleepy tight clothes. U & Me always has great surplus/overstock sweats and tees that can be turned into comfy sleepy tight clothes. They also have a luggage annex where you can get cheap backpacks and carry on stuff. (FTR. For a place on Spadina. Really?)
