Lauren by Ralph Lauren sleeveless dress with tie belt. There are some straps hanging from the shoulder that can be hanging down to the back as shown on picture of the back or they can be on the front. There is also an additional loose tie belt

Very flattering heavy material. It is size M.

PS I am passionate about sustainability and love when items can be reused or used if unused by us to help reduce waste and to support recommerce by supporting reuse of existing goods.
I will also try to reuse packaging as much as I can for sustainability reasons.
