New Talbot dress wearing a size 8 regular. It did give me a little extra room in the waist, but I would not want the petite because I like this length and a six would’ve been too snug in the chest. I am normally a six regular or an eight petite so this would be a size up situation. Fabric is a mix between a satin and a Taffeta. It is really lovely. Size up in the sling backs I go up a half size LTKOver40 LTKWedding LTKWorkwear
