I’m between sizes at the moment (lost weight) but from fashion nova I usually buy L -1X. For this dress, I bought 1X. Wayyy too big. So I reordered the L. Also way too big. It wasn’t as baggy as the 1X but still super big ( unlike other L dresses that I’ve ordered from here). At this point, I’m stuck with the horribly fitting L and will have to make it work. I guess a small would’ve hugged my curves.
