GET THESE JEANS!!
Special Size: Wide Leg Crop, Size: 12, Color: Iced Blue Light Wash, Special Size: Wide Leg Crop, Size: 12, Color: Iced Blue Light Wash
I ordered these jeans because they were recommended by a youtube influencer and I have 0 regrets! They are a fairly heavy denim with just the right amount of stretch to them. I'd consider them to be mid to high waisted since the closure is right below my belly button. However, if I hike them up a bit they sit right above the belly button. I washed and dried them with little to no shrinkage. Length-wise they're slightly cropped on me, and fall right above the ankle. These jeans are honestly SO versatile because they look great with ballet flats, heels, tennis shoes, AND suede or leather ankle boots! Since I couldn't decide, I ordered them in two colors (iced blue light wash & medium blue vintage), and I love them both!! For reference, I'm 5'6 and 170 lbs. I ordered size 12 and they fit great. Highly recommend. You CANNOT beat the price for this level of quality in my opinion!!

My everyday Jean
Special Size: Wide Leg Crop, Size: 8, Color: Medium Blue Vintage
They don’t have much of a stretch to them but they do get a bit more lose around the waist when you wearing often. Got a size 8 was tight but after a few uses they got perfect. Be Definitely is a thick jean material tucks in any unwanted over hang. Don’t tumble dry they do shrink

Good Jean for the price waist hips run small
Special Size: Wide Leg, Size: 18, Color: Black
These pants are good for the price. I needed a pair of wide leg black jeans and the price on these was good. Reviews said the waist was small. I’m a 16/18. Got an 18. And the high waist (up to my belly button) fits snug but has a little give. Still comfortable to wear. The butt thigh area fits snugger than most wide leg pants but again not so tight or uncomfortable to not wear. The fabric is a brushed Jean fabric not just a woven cotton Jean so dog hair sticks to it like glue. They are a heavy quality fabric so not a summer pant. They are a keeper for me. If a gain a few pounds I can these being a no go.

Love these jeans
Size: 12, Color: Iced Blue Light Wash
These a comfortable and flattering pair of jeans. They are length is too long for me but, they have a wide hem and taking them up one hems length makes them a perfect fit for me. This is an easy fix if they are too long. They are well made and a good value in today’s market.
