What makes you feel 'fancy'?

(Apologies if I do not respond quickly, I have a chronic illness that can impact my cognitive abilities and stamina.)

I am turning 40 this Spring and have decided it's time to nurture my inner child and become the 'fancy lady' I always dreamt of being.

What makes you feel fancy, classy, or elegant? Is it something you wear? An activity you do? An item you use? A phrase you say? Anything really.
