The luxury fragrance gift for men, Amouage Gold for men, created by perfumer Guy Robert. 50 ml Eau de Toilette in a lead crystal bottle with 24-carat gold plated decorations. As an added bonus, the floral chypre scent is highly borrowable (I like it better than the women's version). $215 at Parfums Raffy.
If the above is too rich for your blood, try the Fragonard Coffret for Men, with five 6 ml Eaux de Toilette (Eau de Hongrie, Suivez-moi, Santal, Vétyver, and Concerto). "For men who want to be like no-one else". At Four Seasons, $18.
For men or women, Carol's Daughter Love Butter for dry skin, "made on a whim one Christmas as a gift for some special friends and customers", with honey, cinnamon, brown sugar, vanilla and amber. $18 for 8 oz at Carol's Daughter.
For the budding perfumer (ages 10 and up), a Perfume Science Kit, with a 48 page full-color manual, eight perfume oils, two decorative flacons, and an atomizer. $59.95 at The Met Store.
For the grown-up obsessive, the Le Labo Olfactionary. I'm pretty sure I've featured this in a gift post before, and I'll just keep doing so until somebody breaks down and gives it to me. 40 essences (2.5 ml each) to "train the nose", $490 at Barneys.
The stocking stuffer: Jasmine Mint Toothpaste by Marvis (with fluoride). 75 ml, $8.95 at Sesto Senso.
