I haven’t bought many clothes lately, but it wasn’t so long ago, that in order to find pair of jeans that fit, I would have to take about 50 pairs to the dressing room.
Quality control was so bad, that even the same size & the same style & brand, fit differently.
This was at Nordstroms, and the clothes weren’t inexpensive, albeit it was in the juniors dept, so they may have been made cheaply.
