Hey Jordyne,
I don't have any clothes to pass on to you, but I can tell you that all my winter gear pretty much came from the Salvation Army. Instead of shoe covers, I put sandwich bags over my socks. At SA I bought runners tights to wear over my shorts, and a couple of polyester or other wicking fabric turtlenecks for under my regular jerseys. The only real investment I made was in a durable and high-vis windbreaker, and even that I bought used (here on TE.) I found I didn't need arm or leg warmers because the tights and long sleeved turtlenecks usually fit the bill. I am pretty proud of some of the great gear I have found at thrift stores - if you go in knowing what you are looking for, you can find a lot! I found a great underarmour turtleneck (in the men's section), a nice orange tech fabric jacket (for non windy days), and a pair of bmx cyclist gloves in the boys' section. For me, if my toes and fingers are warm and useable, I am usually happy. I wear a no-frills cap with ear flaps (yes, found second hand) under my helmet, and a bandana on my neck for when I need to cover my nose/mouth on really cold days. This is why I have no gear to give you because it's all this used non-name brand gear that I cobbled together and have been using for five winters straight. Oh also if you have an old holey wool sweater, put that over your polyester/wicking shirt, then a light shell/windbreaker over that and you are covered down to like 10 degrees with wind! The plastic sandwich bags work just fine for the toes, but better if you have wool or alpaca socks. Good luck!
