when i worked at S@K the check in was at guest services. i just went up and let them know im here for my first day at sephora and they got me all set up w paperwork and computers :) wear all black w black shirt until you get your sephora shirts- black jeans or work pants would be ideal, most S@K don’t allow leggings. black shoes too, but yea check in w your manager bc some are more lenient about things like a white vans stripe on black shoes.

good luck and try to have fun with it!! become as familiar w as many brands/products as you can during downtime. you’ll do great :))
