Morning, students. Let’s do a word problem.

What do you get when you combine one jewelry maker, one popular LES store, and a talent for design?

Answer: 7115, a new line of blouses, dresses, and rompers from cheerful shop owner/longtime maker of baubles Szeki Chan.

Chan keeps it simple with summer-weight silk, linen, and cotton, plus easy-to-wear cuts. Study (a cocktail) outdoors in a color-block shift with tie belt or sundress with contrast piping. Preppy Peter Pan-collar shirts and mullet-hem shirtdresses — one cap shouldered, one sleeveless — are too cool for school.

She nails a flattering formula with elementary colors (cobalt, navy, olive, orange, aqua), clean lines, and prices from $78 to $178 (you’ll only feel like you’re cheating).

Class dismissed.

Available at Szeki, 157 Rivington Street, between Suffolk and Clinton Streets (212-614-3138 or szekinyc.com).
