Just got this jacket in and it is so cute! Threw it on over my wide cropped jeans and a T-shirt with flats. Sizing starts in XS petite and this is definitely a very wide cut, swingy fit jacket . The length and the sleeve length fit well on me. 100% cotton. Un-Lined. I do not shop at Old Navy often but this is a good one! Linked to other blazers that I have from there too - XS petite is a loose fit on me. More relaxed boyfriend style on me than “fitted” LTKFindsUnder50
