Unsure whether I should keep this dress I thrifted or if it's just unflattering

(I apologize for the mess and the dirty mirror but we are in the process of moving) I usually dislike dresses of this length but I really liked the details on this one. I feel like it's a bit unflattering and I'm unsure whether it's worth it to keep it and do some modifications, like adding extra fabric to make it long or making it short instead.
