Woo hoo! Boss man declared that all employees can dress business casual, like, on a daily basis!

Of course, that was months ago, and you’re still sporting the old suit and button-down look.

Ditch the dress shirt for a fine cotton tee from Gytha Mander. Not your traditional T-shirts, they’re stylish, collarless fitted numbers splashed with sophisticated designs.

Ladies can choose from adornments like the interlocking, vine-like Filigree, the zoologically inclined Animal Kingdom, or the aptly named Gaudy Stripe. Men can return to their youth with the M.A.S.H. — which puts the childhood Mansion, Apartment, Shack, House game on display — or go preppy with the Argyle.

Once you’ve secured a tee, Gytha Mander suggests that you customize it — by slashing the neck three or four inches deep from the center. Casual? Certainly.

But definitely not business as usual.
