Too large
The dress is too big. i got size 4, after checking the measurements chart (for reference: 5'7", 125 lb). it is too wide, not as fitted as in the picture. the cut is too deep (might work better for a bustier lady, but looks pathetic on me). 

the pattern is too bright, much brighter that in the picture (i got red pattern). it's not that the photos represent the colors inaccurately, it's just... the colors are much more vibrant in real life.

the material is heavier than i expected.
