Emanuel Ungaro Vintage 1900’s wool coat

Bought from TheRealReal, cannot be returned. Never wore it, still with the TRR tag. The style is beautiful and fabric is soft and comfortable. But the shoulder width is too wide for me. The coat is long. I'm 5'8" tall and it goes below my knees. One of the button loops is loose when it came to me.(see the last picture.
