Trim & slimming
Size: 16 Short, Color: Deepest Dark
I was so pleased to receive these today. Their title says it all. So well made: the fabric is soft yet the weave is tight, the leg is just the right width at the bottom; and it's comfortably stretchy at the waist and leg. Deepest Dark seems like a true jeans color, blue yet somewhat navy. It's not bright so doesn't call attention to itself. Almost forgot -- the front pockets are just deep enough for a phone.

Slimming Look, Not Too Much Stretch
Size: 8, Color: Blue Format
Some stretch but not too much! I really like these. They hug and pull me in well. I’m slim through the hips with a bit of belly. I’m 5’5” 147.8 and these did not give me a muffin top even though I have a flabby belly. The color is exactly as described. They did not shrink after washing and the quality is what I expect as they are Lee jeans. They are very durable.

Button sucks!
Size: 14, Color: Deepest Dark
These are cute jeans and are great quality, especially for the price. I would've kept them, but had to return them because THE BUTTON IS AWFUL. It is SO hard to get through the hole. It's rounded on the edge so there's nothing to grab onto so it actually hurt my fingers to try to close them. I think the lack of stretch in the top was 25% the culprit, too. They were 100% my size and fit perfectly, so it's not a sizing issue. If I could make a recommendation to Lee it would be to rethink that horrible design and use just the regular button that all jeans come with.

Thighs waaay to big, otherwise literally perfect.
Size: 18, Color: Blue Format
One issue- the thighs were huge. Otherwise these jeans are perfect. They fit great everywhere else, quality material and good thickness. Waist is very comfortable. I wanted so badly to keep these but I knew I'd never wear them. I tried to get past the thigh issue, but they just looked silly.
