I'm kinda bitter about workwear being in fashion after catching so much shit for wearing it at an office with no dress code. Many coworkers wore t-shirts and jeans and refusted to bath for f-sake. I worked in a cubicle in a windowless basement office and had zero customer facing duties. I'm a big dude and it was the only stuff in my size that was affordable. I always had some regular sized jackass telling me that I could dress like them (unsolicited by the way) for $X with zero awareness of supply and demand's effect of pricing and availability.
"You can get a pair of jeans on sale for $30" (hint: I can't)
No amount of explaining would make them understand that stores only stock the most popular sizes. No store is gonna buy/make larger size clothing at greater expense then have it sit on the shelf longer. That's why it costs more. Not to mention as bodies get larger the shapes vary more. This is known in women's wear but not mens. They just make the same shit larger, fit be damned. That's why loose fitting work wear is great. You're less concerned about fit and it's durable so you have purchase it less often. You get your money's worth.
I've heard of women who skew towards the smaller size saying that they can get away with childrens' clothing now that we dress them like little adults. As a big guy that's not an option because there is no larger group to cling onto. I've had some of those same braindead coworkers recommend big and tall shops despite being told repeatedly that they have things for people that are big, and they have things for people that are tall, but they have almost nothing for people that are both big and tall. I kept being told that I could get a suit for $200 (despite nobody other than managers wearing suits) but those are effectively just pinstriped trashbags made out of paper towels. I'm serious, those things were transparently thin and shapeless. Then they tried to make me wear custom suits which was out of my budget. I told them if they raised my salary by the cost of a wardrobe filled with custom suits I'd consider it. Those things started at $2k a suit, not counting the shirts, and shoes which are large as well.
