I’m 5ft4, bust 32, waist 26, hip 35.5in and ordered a size Small.
The dress fits great for a loose look. I’m not sure about the collar with my body type so I have been folding it in or wearing it almost all the way unbutton with a white slip dress. Personally I think it does need a slip especially just in case I end up in a situation where stringer light’s shining through— like standing in front of a window with direct sunlight ^-^
