How do you say ‘thank you’ in the language of fashion?

It’s 2:44AM and I couldn’t sleep. I’m just curious — and this is a completely hypothetical question btw so don’t make any assumptions — don’t jinx it. What would you get

Vivienne Westwood
if she sent you a wedding gown worth US$22,760? I mean, a thank you note simply won’t suffice…

Carrie Bradshaw, Sex and the City Movie, Vivienne Westwood Note

I don’t know about you but Carrie friggin Bradshaw better frame that note.
