Problems with pantyhose?

i just started a new job 2 months ago.in 2 months ive went thru maybee 11 pairs of pantyhose.im not buying drug store brands so there s no excuse.ive tried hanes sheer and both are destroyed after 3 wears.i have to keep another pair with me in my purse not just for work but even im out with my girlfriends.its not that i dont have enough i have a box full.but it seems they start shredding the second after i put the hose on.another brand any gals know of thats not toooo much money but will last after 3 wearings without me having to clean up with theme or wind up giving theme 2 my cats to play with???thanks
