The best jeans description depends on fit, fabric, wash, and occasion, with popular fits including straight leg (timeless, consistent width), slim-fit (modern, snug but not tight), bootcut (fitted through hip/thigh, flares at ankle), and relaxed/loose fit (roomy for comfort). Look for stretch (like elastane) for comfort in tighter fits, and choose dark washes for a more formal look versus lighter washes for casual wear. Fit and wash are also influenced by body type, with dark, minimal-detail jeans generally appearing more slimming.
