I like high leg, plain white cotton ones. Size 10-12. Not frumpy, but not skimpy.
My existing ones are P.....x, (well known brand). They have been very good, but have not bought any for a while as I bulk bought last lot.
Looking online however, the reviews for hopefully the same ones are not encouraging, the usual- thinner material, flimsy, just not the same quality as previous.
I flukily bought a 3 pack of M&S high waist pants 2 years ago. I found they were perfect so went back to get more and they were on 3 for 2 so I bought more. What luck. I'm still happy with them and they wash like new. Bet I'd never find them again though.
