I prefer not to state for a number of reasons, but multiple large national chains, both department stores and clothing stores, ranging from discount to upscale. I finally found a menswear store which carried shirts that fit, mid-market, as well as dress slacks. Jeans turned up at a large retailer.

I also confirmed the sizing changes with multiple store managers at multiple retailers. It's possible they were lying, but comparisons with identically-sized earlier purchases showed that the sizes had been modified.

It's also become rather evident that numerous large retailers are in all sorts of hurt. Ironically it's the ones which are furthest behind the fashion curve which tend to have sizes that fit, but the in-store organization, stock, and staffing are abysmal at many of these.
