It will be a while before you let your daughter wear a little black dress. A long while.

A little gray dress, however, is an entirely different story, thanks to Whitten Grey.

The new line is ethically made from organic cotton in soft colors like cream, white, and gray (of course), with simple details like flutter sleeves, contrast stitching, and understated bows.

Best of all, to help others and teach small shoppers the importance of giving back, for every dress purchased, Whitten Grey donates one to a girl in need through its philanthropic arm, Project Little Grey Dress.

Just try not to buy too many.

Or you’ll find yourself in the red.

Available at Proper Topper, 1350 Connecticut Avenue NW, between N Street and Dupont Circle (202-842-3055); 3213 P Street NW, at Wisconsin Avenue (202-333-6200 or propertopper.com).
