Guys aren’t bombarded with the usual binders of swatches and style-preference questions at Manuel Racim (44 Hudson St., nr. Chambers St.; 212-233-0417), a custom-shirt shop newly opened by Parisian transplant Manuel Guardiola. Just walk in—no appointment necessary—for a stylist-led tour of the high-tech space: Remote-controlled panels rotate with some 200 Italian-milled fabrics and a magical wall mirror converts into a digital touch-screen, letting customers swipe through options for everything from the type of fit, collar, and cuffs to the color of monogram, buttons, and threading. The shirts, which start at $125, are sewn in a century-old French atelier and arrive within two weeks; your measurements, meanwhile, are saved to an online account for future bespoke shopping via manuelracim.com.
