I'm with Liza. I love arm warmers, but not leg or knee warmers. For the arm warmers, I like Sugoi. I think I got them at TE. I'm on the thinner side (but not stick thin) and their grippers hold w/o being too tight. They might offer them in different sizes; I can't remember.
Instead of leg warmers, I just wear knickers. I have some PIs that cover my knees and some Shebeest that cover down to my calf. I find them pretty comfortable even once the temp starts to rise.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
