um-that's a movie-as in fantasy/fiction-not based in reality.
the reality in the region we live in is-if you were to arrive at the international airport nearest our home (spokane but not in spokane 'proper') the nearest towns have no second hand stores, goodwill, or salvation army. the town we are in has only 2 stores that sell any type of clothing-JEANS and thermal long johns. in spokane 'proper', depending on the day, you might find a clothing store open till 5 or 9, or none at all.
when we lived in the napa valley which is known for country club and high end weddings, a traveler with lost luggage could be even worse off. if the traveler arrived in angwin they would find NO clothing stores. if they arrived in st. helena, yountville or calistoga so long as they arrived before 5 p.m. on certain days of the week they might find either insanely overpriced designer items or trashy wine themed t's and shorts, but otherwise little else (wedding rental wear or that aquired through thrift stores ala 'my cousin vinny' was only available multiple towns away at stores that closed even earlier in the day). in napa 'proper' the choices would again be limited to those stores open only until the early hours of the evenings-and those being primarily outlets featuring off season overpriced designer handbags, and boutique lingeree.
speaking as someone who traveled on buisness to lax where my luggage was lost the evening prior to an important presentation, despite my own and the hotel concierge's best efforts to locate a store for me to aquire appropriate attire during non retail hours-it may look easy squeezy in the movies or some d list reality show to pull off finding replacement clothing, but in the real world .-when the store closes, it's closed.
