Scents from the "everyday luxuries" line have been popular in our local middle school. They are dupes of designer fragrances. Honestly, I would check out what scents are trending on TikTok and go with that. Or go with a bunch of travel sizes in various scents so they can mix and match to make their own blend.
My granddaughter is 16 and loves Vanilla scents. I usually get it at Victorias Secret as there is one there, she prefers but Vanilla seems to be favorite for her and her friends.
I don’t know if they still have it right but before Halloween there was a scent that was soda and vanilla and every year at holiday time I buy a few bottles of Vanilla Bean Noel shower gel and body lotion to last the year using it once or twice a week.
My teens girls love this brand of lotions instead of bath and body works and they usually put out some nice gift sets for the holidays. https://soldejaneiro.com/
