This is my fav St John jacket. I got talked into buying it and ended up loving it. It is a knit; different from any other St John I have seen. It has kind of an oriental look?? I could not find materials tag?? it feels like a cotton blend with wool. Not as hot as a lot of ST John jackets. great feel to the knit. see pic. The colors are fab (choral, grey, black and white) and go with anything from dress slacks to jeans. A great addition to any closet. Just dry cleaned. great shape, like new. Pls see pic where the sleeve hem needs some tacking , but I never noticed it when I wore it. (with collar it feels a bit like Jackie O, love that look).
