Catherine Ogust rare VTG rainbow dress

beautiful rainbow print 70s tunic dress by Catherine Ogust for penthouse gallerywith original belt!!! super hard to find with those. has pockets! this fit me as small but could also accommodate a medium as well (no size tag). no material tag but feels like cotton to me.being vintage and pre-owned,there are some flaws: white not as crisp white as it once was,and there are some faint marks throughout- not very noticeable at all but see pics pit to pit 19 in,length 38 .5 in
