Red formal dress size 2

This dress was from 2018 fall season from a brand called sixdo I bought this in Vietnam, I had this tailored to by body and I am a size 2. I’m 5’7 and the dress length is down to half of my calves. I bought this for 1100 I think and that’s the tailored price but if the dress is regular sizing then 850 or 900. the color is a dark maroon *heavy garment* it is not lightweight at all
