Hannah Louise Poston has two videos on this subject. She really likes the shade “Gone Greige” by Maybelline and she was looking for a replacement because she thought it was discontinued. (It still might be, but she found one direct from the brand site.) The first is her attempt to dupe Gone Greige specifically and the second is testing out “weird” drugstore lip shades. These might help you. Also, in a recent video she tried on some Unearthly Cosmetics shades which are of the same ilk.
Foundation isn’t a good idea unless you’re rebuying a favourite, since finish matters a lot and you need to be sure they have their match which can be hard to get.

Lip gloss is one of the safest things to gift. Then eyeshadow. Highlighter or blush after that, but that’s not as easy to do without knowing undertones and being familiar with their existing collection closely.
