Cute but no so comfortable
I previously owned a white sperry leather shoe that I bought from Marshall’s for about $35 & absolutely them, they were so comfortable , cute & great price.After running that pair down, I decided to buy another pair and found out the shoe was discontinued. The closest thing to what I had is this, the white crest vibe in leather. I was disappointed that this shoe was not as comfortable and didn’t fit quite the same. The back ankle part of the shoe caved into my skin and hurt. Sadly, I do not recommend this shoe for much walking. I hope Sperry decides to make this shoe more comfortable because it is cute.

Love these jeans, so soft and lightweight but with all the usual Levi’s class. I bought them in three different colors. They’re so well fitting and comfortable to wear. Im 5’5 140 pounds and it is true to size. The perfect fit every time.!

Classics! Good material with no stretch.
Size: 28, Color: Verified Vintage
I am in love with these jeans. I ordered another pair in a different wash. I also sized up two sizes but I like the looser, slouchy fit.

I love these. They fit perfect in the waist but are roomy else where.

My favorite ever jean, I have a pair in every color
Size: 26, Color: Not My News Channel
I’m a little lanky (5’9”, 125-130lbs) and I want to like wide leg/baggy jeans so bad but every time I try them on, they look ridiculous on me. I look like a straight line in them, or they’re so baggy I feel like I’m wearing a costume. These have the baggy look I’ve been searching for for years but in an understated way that doesn’t make me feel shapeless. I’m also convinced that the buttons are more flattering over the fupa than a zipper. It’s like a hidden corset vs. a zipper that contours to your shape. If you’re in between sizes, definitely size down. Even if you’re not, you may still want to size down or buy both and return the one you don’t like
