What level of formality would this velvet dinner jacket be?

[rondo]

Not to dissuade you from your purchase, but the image (presumably from "makeyourownjeans" or "studiosuits") is not of their product.
It's an image of a Hugo dinner jacket that has had the shirt and trouser colour doctored (darkened) and a watermark added over the top
I'd personally be wary of any vendor not using pics of their own product.

Thanks for the heads up. I have another jacket from this vendor which I presume is an original that worked out well. I'm just here putting things out trying to get as much information as possible before committing to the next purchase. Thanks.

Edit: I have removed the vendor from my list of clothiers. Regardless of the quality of past purchases from them, I do not knowingly buy from people that steal intellectual property from other people. The search continues.
