Choose based on fabric weight, fit, and intended use. Consider wool content and whether you prefer a slim leg or a more relaxed silhouette, then select a shade of grey from Theory's classic or signature lines that pairs easily with tops and outerwear. Ensure the size allows comfortable movement and layer underneath if needed, and check care guidelines to preserve color and shape.

The fabric composition and weave weight (GSM) are the most complex attributes to evaluate. Look for wool percentage, any elastane for stretch, and whether the knit provides smooth drape and good recovery. A higher GSM means warmer, while a lower GSM offers lighter layering; the knit structure also influences pilling and durability. Always follow washing instructions to protect the fabric.

Beginners prioritise comfort and versatility, while pros focus on precise fit and fabric quality. Beginners should choose mid-weight wool blends with good stretch and a simple, timeless silhouette that can be dressed up or down. Pros will check exact measurements, opt for tailored lines, and prefer a durable grey with minimal pilling and reliable shape retention.

Follow proper care to maintain shape and color. Wash cold on a gentle cycle with wool-friendly detergent and avoid high heat; lay flat to dry or hang to dry as recommended. Remove pills gently and store folded to prevent creasing. Pair with neutral tops and jackets for a polished look that works in both casual and office settings.
