Not wishing to be a worrywort, take a longish skirt and thick tights.
On my first skiing trip I allowed myself to be persuaded to try a blue run as I’d “done so well” on the nursery slopes, screwed my cruciate ligament, leg in plaster. Had to borrow a mini skirt and tights from a tiny friend, wore one leg of the tights, the other leg kept the top of my cast warm(
Really good gloves.
Second and third getting really strong sun screen, make sure noses, foreheads and, especially, ears are covered.
Decent hat plus something soft to wear around your neck, ski jackets can rub, I had a snood that I could pull up if necessary, plus a headband for my ears. What you wear will depend on whether it’s sunny or dull, you need to allow for both.
Goggles are are a good idea.
As a learner, never go off the baby slopes without an instructor!!!
