If you know one.september and you know what's good for you, then size the heck down. maybe even two sizes if your particularly slim or want the dress to fit tighter. any way, this dress is simply scrumptious! the embroidery at the bodice is so detailed and pretty. the layers are light and soft like silk (but it's rayon/poly) and the sleeves are sheer and voluminous. i actually prefer the sleeves rolled up because they are too long. neckline features a slit-v with two hooks to close if wanted. co
