Perfect
I just got this in the mail & had to immediately write a review. i love it!. i took a risk & ordered the xxs, which i assume is a 00. it fits me perfectly so i would say it runs large. i'm a true dress size 2 but usually wear a 0 or xs in us sizing. the shoulder length from seam to seam is about 14 inches. i'm 32c-24-34. hope this helps!
