Sainsburys jeggings - saggy knees in no time?

[Whenisitmysleepytime]

I bought some khaki green jeggings in sainsburys yesterday for £12.50.

I'm not sure about them now. They look good on but
A) I'm not sure what to wear with them
B) will they turn into saggy baggy wrecks after a few wears?

Can you advise me on either what to wear with them or whether they're a waste of time :)

I got their blue jeggings a couple of years ago. I probably washed them about 5 times before they went baggy at the knees. I wore mid-thigh length tunics and knee high boots.
