Several of you requested that I do a gift guide for him, so I hope this proves helpful! A lot of these items are things that I know my guy likes - Burberry cologne, J.Crew socks and shirts (they make "tall" if you have a long & lean guy!), Travelpro luggage, personalized pens (I gave Christian an engraved Tiffany's ballpoint pen for Christmas you can see here), gifts for the dog lover and so on.
Worse case scenario - give him a gift card to a nice steakhouse and a batch of cookies. What guy wouldn't like that?
