For rank newbs, first time on the slopes, IMO they can't be sure if they even like the sport to invest in it.
Sooooo... simplify everything. Do what my friends did when they took me out on the slopes for the first time.
Told me to spray my jeans and winter jacket with waterproofing for camping gear, wear a set of thermal underwear (regular dept. store kind) under my jacket and jeans, get long wool socks and gloves. Rent everything else at the resort (get a lesson fo sho). That way you can change things out (like boots) if they don't fit quite right. Learn to ride. Then, if you like the sport, go get kitted out. If you don't like the sport, you still have your jeans, socks, thermals and gloves to wear around town.
