NATIVE HAWAIIAN islands or Asian raincape and skirt c1890 antique SOUTH SEAS

I was told by a respected Boston Harvard school archologist that this handmade native Hawaiian tribal TWO PIECE outfit dates to around c1890 !! and is very rare complete. He placed the value at $12000.00 I am not an expert and am telling you what was told to me. I was given a verbal authentication as c1890 Hawaiian but this is the professors opinion only so could be some other native creator. from a fine art. antique and rare book expert collector. Overall excellent condition with some staining on coat and some collar wear SOLD AS IS not authenticated NO RETURN so please look at pictures and ask any questions prior to bid, Tight heavy weave super scarce museum quality set HAND MADE one of a kind collector piece....Enjoy
