Where, exactly, is Garnet Hill and how do I get there?

Despite my best efforts to STOP the onslaught of the glossy catalogs that show up uninvited in my mailbox and stuff the recycling bin, they still show up.  And some of them are like shopping porn.  Of those that I cannot simply place in the bin without lovingly paging through them are:

• Athleta.  Because, if I stare at this catalog long enough, I will get toned abs and learn how to surf
• Boden, which takes me to Hampstead Heath, where I spend my days at the Tate and my nights at fabulous soirees with people who know the Royals
• And, most scintillating of all, Garnet Hill.

So, where IS Garnet Hill?  I know who lives there: beautiful blonde women who can wear casual-chic all week long and who have adorable daughters and whose handsome husbands show up once a year at  Christmastime, draped in cashmere and wearing slippers.  These women are tall and athletic and have amazing hair.  Even though they don't work in traditional business, evidenced by their attire (except, maybe, the Eileen Fisher line, which I'll get to in a moment), they can afford Chan Luu jewelry and $350 Frye boots and lots of cashmere. 

And it doesn't stop there.  No!  It migrates to their homes, where their housekeepers make up the beds with Eileen Fisher quilted silk comforters that cost more than one month's mortgage.  And the sheets that are made by hand by elves in Switzerland from the strands of little Alpine flowers.  And the  PILLOWS!  And the RUGS!  And the tchochkes!

It's enough to make my heart race and my credit card leap from my wallet because if I get the cashmere sweater, surely I will grow seven inches and suddenly sprout golden highlights in my hair and my husband will wear SLIPPERS and I will go to bed at night in the most beautiful bed EVER which will NEVER be wrecked by my kids, because my boys will morph into well-behaved, beautifully dressed little girls.  And I will reach into my Italian leather bag to replace my wallet and I will be HAPPY!

So, if you know how to get to Garnet Hill, please let me know.  I know I'd be happy there.
