HI, is this Rag and Bone pair of jeans authentic? I've searched and searched.

I've spent an hour trying to figure this out. Any help would be a appreciative. 

Thanks!

There is no size.

They are fine. Sizing might be tricky if you are hoping to resell. You could compare measurements to other listings to get a rough estimate.
