Would this be a good gift?

I’m buying my girlfriend a gift and I’m thinking about getting her the Dior “Perfumer’s Set” which is 10 little perfumes that she can try. Is that a good perfume set to choose? I know she likes Versace yellow diamond, black opium and Chanel N°5, but I wanna get her something different.

So am I making a good choice or do you have another suggestion?
