Alexandra's Emporium Girls Patchwork Sleeveless Dress With Tie Back Size Large

Alexandra's Emporium girls patchwork a line tank top size large. Multicolor fabric squares make up this dress, two front pockets, tie back, full skirt. This dress appears to be vintage but I am not a vintage expert. It is in excellent preowned condition. Please pay attention to measurements as the sizing does seem off.  I tries thus on a girl who wears a size 6 and it didn't fit so I think it's for a toddler but can't be sure. Measurements are approximate and as follows: 12" pit to pit, 28" long Design rundown: vintage 70s hippie eclectic Stevie Nicks classic flower child
