For decades, the conventional wisdom in apparel sourcing has been straightforward: domestic manufacturing cannot compete with offshore production on cost. Labor arbitrage made offshoring the default. Supply chain complexity was the accepted tradeoff. And the idea of producing swimwear —a cost-sensitive, trend-driven, highly seasonal product—in the United States seemed economically unrealistic. That calculus is changing. Not because labor costs have equalized, but because artificial intelligence is restructuring the economics of small-batch domestic production in ways that make the old comparison increasingly obsolete.
