Feels a little large, which probably means it's the right size.  I'm a big guy (6'2'' and 260 lbs) and many yukata just don't wrap around enough.  This one wraps just like the picture.  I call it somewhat large due to contrast effect.  The fabric is excellent, and the belt is sown into one sleeve just like it's supposed to be.  Looks sharp too.  Those are fine stripes making up that color.  Get a real obi if you want a more formal look.  Finally found a vendor who sells Japanese wear for Americans.
