Poorly finished garments. Bad puckered seams, lots of loose threads, and the loose buttons!
I remember when I was a teenager my mom bought herself a beautiful Elie Tahari silk chiffon shirt. She had waffled on it, thought about it, and finally went for it (usually she would buy without a second thought) and waited for it to arrive.
In trying it on all the buttons fell off.
And this wasn't a cheap shirt (and it was a full placket of buttons too!) I remember her remarking that the Forever 21 buttons were sewed on better! They were little buttons and I guess the absolute gall she had to put them through the buttonhole was too much.
I sewed them all back on for her and to her dying day she remembered those stupid buttons falling right off
. I don't blame her one bit.
Not taking care of what you have. Hate seeing/hearing shoes destroyed because someone won't do basic upkeep. I had to rescue several cashmere items from my mom as she was a little lackadaisical in storing them. I got good at patching with felted wool and doing some creative reweaving for a lot of things.
