This is pre-alterations, but you get the picture! I'm getting a little cut off the side and a bustle put in. I'm 5'0" and had a great experience at David's Bridal. They carry nearly every dress in petite sizing at the same price as "regular" sizes. I couldn't go low-cut (I flush when I'm the center of attention. ) Really obsessed with the back.
I have a long torso for my height 4’11” so a petite size dress would have made the top hit just under my bust and look funny so that was out of the question for me but my dress designer custom make the dresses to your size at no additional cost!
I am 5'2! There are tons of options Just be mindful of alterations costs because you will have to get it hemmed. I didn't realize when buying my dress that the more layers on the bottom (and the more detail), the more expensive it is to hem, so keep that in mind!
