Stay stylish and comfortable with this sweatshirt like, gray women's jacket cardigan. Featuring a distinctive logo and button front. Perfect for any casual outing. Shawl neck. Rugby, monogram, prep, preppy, school, academia, fall, winter. IMPORTANT: Listed as a medium, the tag says XL. Measures 18" flat across pit to pit. I think it may be a junior size, or it just runs small?? I wear a women's 8 or 10 and it fits me (I'm in the photos.) The mannequin wears a small. All that to say... go by measurements. 😀 Can most likely fit a small medium or large...
