Ladies size large Design Lab Dress

This is a ladies size Large Design Lab dress I purchased on Posh and it does not suit me. It’s brown/cream snake print with a v-neck and buttons that open it all the way. Has a defined waist with a flared out skirt. This is a super nice dress for the office or night out. There was no fabric tag upon purchasing but I’m thinking a rayon. Please see the above photos for measurements:
