Although the brand is unknown, I'm guessing this is from the mid to late 70s based on the material, silhouette, and zipper type. Definitely vintage, but in good condition. These are single-layer, quite flared pants. As you can see from the photos, they have a simple construction with small belt loops and darts at the hip apex, and nothing else. Unlike the typical 70s style, the thighs aren't super tight, and the thigh width is surprisingly wide. They have a beautiful silhouette when worn, but I don't think that's coming across, so I'll explain it anyway ↓ Since there are no pockets, the waist area is quite clean. The hip darts also help to create a feminine form. They fall straight down to the hem, but instead of being limp, they flare out to the sides. They look straight from the side, and have a beautiful flared silhouette from the front. Of course, when you walk, your knees go up, and this silhouette reverses front and side, and when you put your legs down, it returns to the silhouette mentioned above. They have a quality that you'll understand when you wear them, as the silhouette changes with every step. The elegant and beautiful silhouette is also a great point. These pants have a nice width and a soft, crisp single layer of what seems to be polyester, giving them a flowing feel. Of course, being flared, they also help to make your legs look longer. You can add a center press if you like, and it might change the silhouette for the better. Material: Unknown, but a polyester blend.

I don't think these are suitable for wearing with a belt to cinch the waist. If you absolutely must cinch them, folding the fabric on both sides might help to keep the shape. Condition: A S.
