Ordered a large in the blue baby doll, it says large on it, it is the smallest "large" I've seen. The sizing guide says 37-39" bust, but at a 38, this thing is smashing, if you get my drift. And, due to the "final sale", clause, no return. Hope you didn't get snickered into this one.
Here's the deal - the outfit itself is lovely and the robe is great - but the Babydolls run very small. I am a small at Old Navy, Gap, etc (5'3, 115) - but the small in this Babydoll is so small that I almost got stuck in it when trying it on and almost had to cut it off of my body. Crazy. It runs small - to say the least. The robe is fine and reflects the provided sizing chart - a small is a small. The Babydolls run much smaller than usual sizing - and the sizing chart does not reflect that. There is no way that a S equals a 4/6. I wear a 3/4 or even at 2 at Old Navy and I don't think I would've been able to get an extra small through an arm in this Babydoll. Again - the robe's sizing is correct.
