The most beautiful pattern! Looks as gorgeous in real life as it does in photos. The waist measures 24" flat, but it has a hidden drawstring and significant stretch, so I'm sure it could comfortably accommodate a lot of sizes. My waist is 23" and it fits perfectly if I cinch it a bit. From the website: "The adidas Originals x Liberty London Firebird Trackpants are where elegance meets sport. Inspired by the rich DNA of Liberty and our soccer archives, these track pants are adorned with ornamental details and all-over prints that make a statement. Crafted in a tricot construction, they offer a loose fit that delivers comfort and style in equal measure. The mid-rise waist provides a flattering silhouette, while the knit fabric adds an extra touch of sophistication." Material: 100% Recycled Polyester
