I would give my sister-in-law the Sephora Favorites The Makeup Extravaganza. She is a very busy mum, her son starts pre-school in a couple of weeks and has 18 month old twin girls. She loves makeup and looking glam so this gift would be perfect for her.
I would keep the Sephora Favorites The Makeup Extravaganza for myself, that way my sister-in-law and I can create different makeup looks together.
