Miss Onward vintage Japanese brown and white short sleeve dress

Vintage Miss Onward fitted dress (1960-70s). Short sleeves, graphic print, pleated detail at neckline, fit & flare. Fits like an XS / US 2ish. See measurement photos to be sure. Unlined. Loose threads on inside seams. Back zipper has a hook closure but the grabber side is missing. Belt loops but no belt included. Super cute but I’ve been rock climbing a lot and my upper arms no longer fit in the cute little sleeves, ha. Vintage but I haven’t worn it since I bought it.
