I go back and fourth with sizes 2x to 3x. I got a 2x in this dress and it does fit snug. BUT, it definitely shapes you well & leaves you SNATCHED. I do wish I would’ve sized up for a more comfortable fit but it definitely has that spanx type of snatched so I don’t mind it fitting me tight. beauty is pain! I love this dress. if you usually size up, then size up. if you wanna be snatched and have the curves going off, then get the size you prefer 😌 it’s true to size, but again, keep in mind that it literally feels like you’re wearing shape wear!
