J. Crew Going-out blazer in stretch twill NWT

Beautiful fitted blazer. From the J. Crew site: With an open front and slim cut, it's for those nights you want to show off your favorite top (thus the name) but it's substantially stretchy and structured enough to be worn anytime, anywhere. Like meetings and lunch dates and coffee runs and... P.S. Pair this back to our Pencil Skirt & Cameron Pant in stretch twill and you've got a modern take on a suit. Viscose/nylon/elastane. Standing collar. Back vent at hem. Welt pockets. Lined. Dry clean. Import. Item H2743. Slim fit. Body length: 24 1/2". Sleeve length: 30". Hits at hip. Size 10: 38" bust, 30" natural waist, 40" hip, 31.87" arm length. The site says it fits slightly small based on customer reviews. This was not my experience, but it is fitted. There is absolutely nothing wrong with it, I missed the return window and decided to keep a smaller size.
