HOUSE OF CB 'Carmen' Buttercup Bustier Sundress yellow NWOT size XS

I bought this dress from someone who was reposhing it as well. It came in perfect condition and I never wore it!! I loved this dress but it definitely runs small! The size chart on their website says xs is US size 2-4 but I think it fits more like a 0. It’s the regular A-C cup size.
