Tequila, lime, and salt. Ménages á trois. Jack, Janet, and Chrissy.

Good things come in threes.

One more for the list: These Three Things’s first collection. Courtesy of designers and best buds Quinn J. and Z. Buck, the line’s three smock dresses come in muted color pairings of washed silk and wool jersey.

The Jumper, with its cross ties and button-up tabs, begs to be taken to work. Loosen the row of silver metal buttons on the Peter Pan to transform the whimsical dress into an evening-ready coat. And hold on to summer with the plunging lines on the Bathing Suit Back frock.

Each style can be twisted and turned: Undo the snaps to cover knobby knees, wear it backward to reveal some skin, or crisscross the straps for a high neckline.

Now grab a couple pals and make a beeline for the Regal Beagle.
