Sometimes you do things to make life a little easier for others.

Like reminding your siblings that it’s Mom’s birthday. (Anything to avoid another “episode.”) Taking charge of bill division for a table of twenty. Waxing your no-no special place every freaking month.

For us, it’s introducing you to Key, a cool new clothing boutique on Grand Street. A former artist’s studio, the sunny, spacious, laid-back shop has high ceilings, antique wallpaper, hardwood floors, and a patio in back.

As for the clothes? Well, every piece is special and wearable. The atypical selection includes emerging designers (Jak & Rae) and established brands (Corey Lynn Calter, Lauren Moffat) displayed alongside affordable vintage pieces and flea market finds.

For the assiduous: pretty work attire. For the loafer: resort wear. For everyone: a great mix of coats, cashmere, and shoes.

A chalkboard on the wall lists books to read, movies to see, and cool happenings in the ’hood. You know, the kinds of tips that make life a little easier.

And that’s always key.

Key, 41 Grand Street, between West Broadway and Thompson Streets (212-334-5707).
