No. This is a price increase due to their increased costs. Southeast Asia, home of a lot of manufacturing for US apparel, has been hit very hard by tariffs.
My primary supplier is a multi-national manufacturer/distributor that strictly sells to resellers who further embellish their products (as I do) for end purchasers. (Since semi-retiring, less than one percent of my sales are retail. We sell wholesale to two specialty retailers.) Believe me, my vendor is loath to increase their prices, just as I will be, and just as my specialty retailers will be.
I was warned of a January increase back in August-ish. They've absorbed the additional tariffs between then and the beginning of the new year. As happened last spring, the rest of my vendors will surely issue similar price increases.
Just as I can't absorb these kinds of price increases and remain in business, neither can my suppliers nor those I sell to.
