BALLERINA FLATS: The classic flat remains, through trends and non-trends and trends-ending and detrends, a gold standard. Add orange, bright orange, and you've got a shoe with pow. Adding orange to anything, really, is always a good policy. We spied these Serina Orange Vegan Ballerina Flats at Alternative Outfitters and we liked everything about them. INCLUDING THE PRICE: They're on sale for $28.80. The upper part is pleathery. Pleather! Yes.
