I bought this dress in neon pink and it is a nice barbie pink, so I love the color. Sometimes sequin dresses are super small/tight without much stretch, but I'd say this one runs true to size and is very stretchy. It is really short though! And I found the straps and the seam on the lower back to be pretty scratchy bc of the sequins, but I guess that's to be expected.
I got the dress in small because that’s usually my size but it was kind of snug. I’m 5’4 and it stopped about 2 inches below my butt.
