I'm 5'9", 190lbs & I ordered  Large Tall.
The length is perfect.
They are VERY thin .  Great for me for summer BUT the white requires a longer top!  It's sheer!
Sits at my natural waist.
A little snug over my big butt, but not uncomfortable when I sit.

I gave them 4 stars because I honestly think these are overpriced,  $10.00 or less would be a fair price.
