Honestly I saw the "built-in thong look" and I had to try them and they don't disappoint -- your booty will pop! I love this brand and have like 18 pairs of their leggings now, but this fabric is new to me. It's extremely soft and stretchy and more on the cotton feel side of things (as opposed to nylon/spandex feel). They are incredibly comfortable and feel like I'm wearing nothing, even more so than their "naked feeling" line! They don't have as much compression as some of the other naked feeling leggings (and definitely not as much as their "hugged feeling" line), but these are some of the most comfortable, cute, and eye-catching leggings I've ever owned. You should try them while you still can, when I bought them it said only 5 left in stock. With Prime and Free Returns, you have nothing to lose really!
My regular size fits perfectly. I also bought the Navy and it's true to color, the Antique Bark is like a muted purple. I do wish CRZ Yoga would release some bright colors, like super bright pinks, but other than that I have nothing but good things to say about these and absolutely recommend them. We'll see how the stitching holds up in the wash and through hard workouts.
I don't get anything for writing this review by the way. I paid full price for these because I wanted to try them and am definitely keeping them. I'm just a leggings addict trying to be helpful.
