How does the sizing run?

Small. The listed sizes are about one to two sizes below US and European sizing, so pick the larger size if you fall between two. Check the size chart before ordering.

Is it warm enough for real winter?

It suits fall, mild winter and commuting. The fill is cotton, not down, so it is heavier and less warm for its bulk than a down jacket. For deep cold, layer underneath or choose a down-filled coat.

No. The shell is cotton with no waterproof membrane or coating mentioned, so it handles light drizzle at best. Rain will soak through.

What colors and sizes are available?

Pink, green, black, blue, burgundy and brown, in S through 5XL. The cut is slim fit with long sleeves and a hood.

One coat. Nothing else is included.

How should I care for it?

Cotton shell and fill with a fleece lining generally tolerate machine washing on a gentle cycle and air drying. Avoid high heat, which can shrink cotton fill and mat the fleece.
