Is there a significant decline in quality of clothes recently?

So a few months ago I bought a pair of jeggings from m&s and I noticed after wearing them that the colour had transferred to literally everything - my skin, my furniture, even my handbag. I washed them multiple times but it kept happening so had to throw them away.

I then bought two more pairs and they STINK - I can't even place the smell maybe it's the smell of factory? Not sure but I've washed them multiple times, soaked them overnight and they still smell!!!

It's so frustrating, m&s is one of my favourite shops but they're putting their prices up and the quality is going down.

Has anyone else noticed this? Is it just m&s or everywhere now?
