I think I'm going to go with a lip product because she'll probably use that the most. I was considering accessories but didn't see anything that seemed irreplaceable, especially since she has no special love for MAC so getting their compact versus a regular Sanrio one wouldn't make a difference to her. High-quality HK cosmetics aren't easy to come by, however, since most are made for 5-year-olds!
I'm leaning toward one of the lipglasses -- possibly Mimmy or Sweet Strawberry. Mimmy would be great to layer over lipstick, but since my mom is often on-the-go I don't know that she'd take the time for the two-step application process.
Sweet Strawberry could work since it deposits color, but I don't know how the berry shade would look on her. I look good in berries so that's a somewhat promising sign, however, my mom has red hair and tends to wear red lipstick whereas I have light brown hair.
Hmm...guess I'll go back to the store and try those two specifically on my own lips, and make a decision. Better do it fast, since some of the HK products are already sold out online!
Any ideas for what to get my mom from this collection?
