Cute but run big
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Flamingo Pink
Color is fantastic. Very naked feeling. Runs big. I’m a size 12/14 and usually wear XL with them sometimes feeling tight. I am pear shaped - 35” waist, 47” hip and these fit but were quite loose in the waist. I might consider sizing down if I wanted to tighter. They would be very a bump-friendly non-maternity option

Love these!!!
Special Size: 7" Inseam without Pockets, Size: Large, Color: Ocean Blue
Super happy with these shorts!!! Wore them on a full day at the theme park. Stayed in place and did not ride up. No pinching or constricting. The material is buttery soft and the blue is so vibrant and pretty!! Don’t show every bump and imperfection, but does show some. It’s not totally smoothing. Very work out friendly, heat friendly, running errands friendly. Would definitely recommend and plan to buy other colors. Comfy waist band as well.

Excellent Work-out & Biking Short
Special Size: 7" Inseam without Pockets, Size: Small, Color: Ocean Blue
I love these biker shorts. They have just the right amount of lycra and they are super soft. They are true to size, and they fit perfectly on my 5'2", 125-pound frame. I purchased them for use in bike riding, and I am very pleased with the fit and stretch. The inseam length is perfect for bike riding, and the legs don't ride up my thigh. The only con to all the pros is there isn't a phone pocket. I ride my bike around town, and I would have liked to have a pocket for my phone when going inside a store. These shorts are well worth the price. I purchased three different colors and love them all. I would definitely purchase this item again.

Cute but could use some pockets
Special Size: 6" Inseam Contrast Trim without Pockets, Size: Small, Color: Navy/White
Obsessed with these shorts. They are so cute and comfy. They fit true to size and I love that there is a matching top you can buy separately. I feel like the material is pretty thick and I don't have to worry about it being see through. My only complaint is that there are no pockets.
