Suz, that denim article has great tips. I also like to wash my jeans inside out and never ever put them in the dryer, and I get the waist/seat tailored (a relatively easy and cheap alteration) if needed.
And: this is NOT a nitpick to you, but rather to the author.
I can tell that the author has never shopped for plus size vintage or raw denim based on the first 3 points, especially that first sentence, which is not at all accurate for those outside the size range found in vintage markets.
“Start with vintage: Whether you are a denim aficionado or a student on a budget, you can find jeans to suit your budget and your style if you shop secondhand.
“Raw is best: Raw denim hasn’t been washed and treated multiple times. This is what denim used to look like before we started to sandblast, bleach and rip it to make it look old. Buy a pair of unwashed jeans and let them age with you.
“Avoid stretch: Let leggings be leggings and jeans be jeans. One hundred per cent means the denim in your jeans can eventually be recycled.”
