Yes ma'am it is a size large. I wore it only once but it is a tad bit short so I'd recommend pairing this with leggings or maybe even tights depending.
I'm 5'3", think it will still be pretty short on me? What is usually "short" on one person is usually a bit longer on me. Can you by chance take a tape measure and measure it from the top of the shoulder to the bottom of the dress? Fanned & watching! :)
Im 4'11 and its still short on me so more than likely yes. I actually do not have a tape measurer :/ The only problem I had with this dress was that I had to keep pulling it down because it felt like it was riding up, but Im thinking its because Im a bit on the busty side, that may have been an issue.
