What does the XX-large fit feel like?

It is a relaxed, boxy XX-large cut typical of 90s flannel. Measure a shirt you already like and compare chest and length before buying, since vintage sizing runs differently from today's.

Is this the same as a new Alcott flannel shirt?

No. It is a 1990s piece, so the fabric, cut and check pattern differ from current Alcott styles. Treat it as vintage rather than a current model.

How should I care for vintage cotton flannel?

Wash cold on a gentle cycle and hang or line dry to limit shrinkage and fading. Iron on medium heat if needed.

Is it warm enough for winter?

Cotton flannel of this era is mid-weight, good for layering over a tee in fall or mild winter. For deep cold, wear it under a jacket.

What condition is it in?

It is listed as very good condition for a vintage garment. Ask the seller about any specific flaws such as fading, pilling or loose buttons before buying.
