Product fits well. I'm about 200 lbs and usually wear a size fourteen. I hadn't noticed before purchasing but the straps under your arms that connect the front and back panels are adjustable and elastic. I didn't measure the neck, mostly because I wasn't going to wear it fully buttoned anyway but I saw other reviews saying it was about 16.5 inches so I bought this knowing how a sixteen inch choker fits. Overall the quality fits the price but it seems perfect for the occasional interview or presentation.
