18th gift for dd. What perfume?

[RyanGoslingRocks]

Dd birthday in a few days. Re gifts, we’ve got her a few things but she is also into perfume in a big way (the highlight of our recent London trip was the perfume counters at Harrods). She has bought samples of Byredo, Escentric Molecules and Le Labo. I think she likes Molecule 01 but hasn’t tried Killian Paris or Maison Francis Kurkdjian or I’m sure many others.
She loves “Amazing Grace” by Philosophy, Tom Ford Ombré Leather and Lost Cherry, Lust by Lush and my carefully hidden away (or so I thought) old Dolce&Gabanna red/femme perfume.
I am thinking perhaps of a trial set rather than one perfume which she may not like. Possibly a perfume/scent box subscription. Can any perfume lovers give me some advice please? Does the perfect stop you in the street/intriguing perfume exist?

I did the Penhaligons library tester box (45 pounds-ish) for DD; she now has Luna as her favourite perfme (expensive!)

It was fun to test each perfume every day.
It is very classy IMO.

Can you get her a Liberty voucher and let her go and spend some time and choose something in the amazing fragrance department there?

The Perfumer’s Palette from Dior? Penhalign’s do sets as well. Victoria Beckham Portofino is beautiful, always get compliments while wearing it.

Thanks for the suggestions.
@BlackStrayCat I’ll go take a look, thanks.
@whoopdeedoo thanks, we are in Glasgow so no Liberty near us, we did go there though and spent about 30 mins talking to the Creed rep (had no idea they had so many perfumes!). The nearest place similar is SpaceNK. We are going there this weekend.
@BusyEvenForBee will have a look, thanks.

I second Penhaligons- depending on budget maybe get her the tester box and then a gift card/cash for one bottle of her choosing? If not, even just the testers are fun!

Maison Margiela are on offer in John Lewis atm, I just stocked up on my own and some for presents, they do tester selections too. Or compare the notes of perfumes she already loves and wing it!
