Cute little lemon yellow dress is so 60s with it’s dropwaist and faux pocket detailing. It is a little more body hugging than some 60s which tend to be boxier by design. Our mannequin has a 34” bust and it is snug on her so I’m calling this a small or small/medium. The fabric is soft and fine but irons up quite stiff so I think it is a linen blend and is unlined. Zips up the back. Add pair of sandals and you are ready for a hot afternoon around town.
