Is 100% cashmere worth it over a wool overcoat?

Cashmere is warmer for its weight and much softer, so the coat feels lighter over a suit. Wool and wool blends are tougher and cheaper to replace, so pick cashmere if comfort and drape matter more than hard wear.

Warm enough for cold dry days over a suit or sweater. It is not a rain or snow coat, and cashmere loses insulation when wet.

How should I care for it?

Brush it after wear, air it rather than washing it often, and use a specialist dry cleaner. Store it folded or hung with moth protection in the off season.

Does it fit over a suit jacket?

A single-breasted overcoat in this style is cut to layer over tailoring. Try it on over the jacket you plan to wear, since shoulder and sleeve room is what limits layering.
