Osito 2 Fleece Jacket

Do these run small or a little large? My wife usually wears a small but wears a lot of sweaters in the winter and I’m thinking a medium would be better. Any suggestions?

Photos suggest that it’s kinda fitted.

What you might do is find a coat that she already has and measure it to compare to the size chart.

The women’s jackets are very fitted. If she will wear over sweaters I would get a medium.

Are the inside sleeves of this jacket lined with fleece as well?

It’s all fleece, no lining.
