"Honestly THE BEST SWEATPANTS! I’m petite an thought it would be too long but it was perfect length with my Uggs and shoes! I felt so cute and the fit is beyond flattering. Many complements thus far!"
"So cute!! Absolutely love the milk color. Definitely oversized so you could size down one or even two sizes"
"The navy is super soft and washes well. Fabric is a bit thick and heavy, but very cute. XS isn't too oversized."
"The fit is so much better now! Last time I ordered they were too big and a bit short and now it’s the best fit plus the color and fabric are fantastic."
"These sweats are the perfect length with shoes on and they don’t drag, I’m 5’4” for reference. They are so thick and comfortable. I love them and wear them all the time."
"This is my favorite pants now!"
"The quality is amazing. Love the oversized. I'm a M in most bottoms at CSB cause my hips and butt are large but I got a S and it was perfect. Thought the M would be toooo baggy. I'm 5'1 it's not overly long. I wanna wear these everywhere need more colors"
"Love the length and the shape of the legs and that they’re organic cotton. I could use a small but the medium fit as well. I just wish the rise was a bit shorter because if I wear them low on the hips they give the saggy butt look but otherwise amazing and comfortable."
"Love love love! These are the warmest and most comfy tracksuits pants I own! The fabric is so warm for winter but also airy for cooler nights during the warmer months. The fabric is super light weight but also great quality. I also love the colour!"
