The current favorite with the son studying for the bar exam (smart guy, everyone knows that shopping is therapeutic) is General Knot and Company. This is the most charming purveyor of bow ties and neckties I have ever had the pleasure of stumbling across. (They share my penchant for driftwood too, judging by the design of their website.)
General Knot is run by two men who met while waiting for a train to New York City; one was a fashion design director and the other a software architect. They share "adoration for...all things vintage, and an unyielding desire to create enduring products." They hunt down vintage fabrics at estate sales, auctions, and they also buy material from collectors.
I love shopping for men's clothing. There's something wonderful about cotton shirts and handkerchiefs and blocky sweaters that are classic and timeless. I wrote recently about buying linen shorts (for myself) at Banana Republic, and of course every summer I have to buy a new handkerchief--someone has discovered my stash, which looks a bit depleted....hmm.
