In the world of bags, there’s good and there’s bad. Goodie bags = good. Dirt bags = bad.

But business bags? Well, those can go either way. Theresa Kathryn laptop bags, however, should take out all the guesswork.

Take the Angelina, a sexy number that’s vixen on the outside (butter-smooth calfskin exteriors in black, cognac, and snow) yet surprisingly practical upon scrutiny (a silk-lined interior has a padded compartment for your laptop and two roomy pockets with hooks for pens, sunglasses, keys, and phone). The bag comes with a removable silk evening clutch that will leave run-of-the-mill business bags feeling inadequate.

All that, plus a portion of the proceeds from every one sold goes directly to the Theresa Kathryn Foundation, a public charity supporting women’s causes all over the world.

Gotta love mixing business with pleasure.
