I got my regular size and it fits perfectly BUT the fabric of this dress is pretty thick and warm and also not very stretchy, therefore I won't be able to wear it for the occasion needed because where I live is 110°F at the moment and this is the kind of fabric that makes you sweat so I'll have to wait for winter to wear it. I still give 4 star because if you live in a colder area and need a dress for a night out it's worth to buy.
