Bathrobe Vintage Miro Print xxl Rene Lezard

Vintage Rene Lezard Bathrobe XXL in very good condition. Probably from 1980 With Joan Miro inspired print. That is truly one of a kind, I could not find more information. It is in very good condition, but 2 little flaws, see pictures.If you look at the label it clearly has some discoloration, I washed it but no chance to get it out. On one shoulder there is a yellow stripe and I cant figure out if that is color or part of print. Measurements are 53 in length and 29 pit to pit 153
