Good show.
Interestingly, my fancy little daughter does NOT mind shopping at the Goodwill. By the way, I live near Goodwill HQ (well, within driving distance), so we've got the one big original store (plus a few small ones).
Just like her great-grandmother, you could drop her off there in the morning, and let her spend the whole day, as recreation.
They used to even have a cafe, and a little museum, that were kinda fun. The museum was full of donated artifacts of some interest. Like old diving suits, and a hydroplane. I think those are long-gone.
Anyway, it helps that my daughter likes being "creative". So, she can often figure out how to alter or mend old clothing, plus she likes to find "vintage" looks too. If worse comes to worse, sometimes she'll take something apart and use it as a pattern.
