This is a vintage sleeveless dress from FENDI in the 90s. There is an "F" metal charm at the hem.
Some stitches are snugged a little bit at the hem as shown in the photo, but overall condition is still good.
Brown and grey 2 color mix dress would make you look even more elegant and sophisticated.
Although the size shows 44, you may even wear it with a tight high waist belt and make it mod look.
