Meaning the very rarefied air of Floris and Penhaligon's.
Extravagant Necessities in downtown Frisco has several bottles of the Floris Cefiro, No. 89 and Santal. And a single tube of Santal Shaving cream.
There were no other ancillaries in stock but the owner said she was happy to order whatever I wanted and would have it shipped straight to me so I wouldn't have to drive back to Frisco. Seems keen to help.
Centre in Mockingbird Village has Blenheim Bouquet big and small bottles, shave and after-shave balm. They have big and small bottles of the Quercus and the Endymion. No Fern, Raquets, Hammam, etc.
In terms of ancillaries they seem to have most of the Blenheim, but little else.
