1920s Margaux Flapper Dress

I planned to wear this dress to a wedding and have had sizing issues with Unique Vintage before, so I was extremely careful to follow the provided size chart and took my fresh measurements to make sure it was the correct size. It fits horrendously. This item is also obviously not patterned for a plus sized body. The middle section is too long to sit nicely at a natural waist, the bust section hits about midway down my bust, and if you pull it down to sit where the neckline should, the shoulder section gaps and sits terribly. This is not worth the price tag and it's clear that UV is moving to fast fashion practices and keeping their slow fashion price tags. This dress isn't even lined and the system won't even let me return the dress to get a refund, so I'm stuck with a poorly constructed dress that you can't pay me to wear
