As we draw closer to the reopening of Montgomery County — date still to be determined — our stores are preparing to welcome back customers to an altered shopping environment. Masks will be de rigueur, of course, with some places handing out gloves and sanitizer. Staffers will be cleaning constantly, enforcing social distancing and limiting traffic in their stores. Bra fittings, makeup testing and other “high-touch” services will no longer be offered. Fitting rooms will be scarce at some stores and closed at others; “try-it-on-at-home” will be the norm. And all that stuff you end up returning? It will have to be quarantined and/or disinfected before going back to the racks. Lastly, forget about bringing cash: A lot of stores will no longer accept it.
