Dress code: casual Friday (black tie optional).

Dang. Your trusty tux T-shirt is missing a button.

Try suiting up in Quail, the debut clothing line from L.A. designer Michelle Nguyen. Her affordable pieces are peppered with just enough smart, formal details to make them special, but they’re simple enough to wear any old day.

An ever-so-slightly promish Grad dress comes in flirty cocktail or prim tea length; the fluttery short-sleeve Empire dress will take you from day to night (or maybe night to day). Available in royal blue, the black-bibbed Tuxedo camisole also comes as a mustard-hued dress with a pin-tucked placket and scoop hemline. And with the minty green babydoll dress or high-waisted skirt with pockets, you’ll be covered for any occasion.

Looks like you won’t be needing that trompe l’oeil ribcage tee after all.

Available at Filly, 8032 West Third Street, between Crescent Heights Boulevard and Laurel Avenue, Mid-City West (323-653-7200 or fillyfilly.com). To see styles, go to qisforquail.com.
