This is surprisingly high quality. Wore it for a school colonial simulation activity -- everyone was super-impressed and assumed I'd spent $200 or more on it.  The white patterned portion of the dress is a nice linen/cotton type fabric, and the navy blue is a mid-weight satiny fabric, not the flimsy costumey kind. Not itchy and the fabric is breathable.

It does require a hoop skirt underneath to look right, so be aware of that.  It will be far too long for most people without it.  I'm 5'5" and wore it with wedge boots underneath and a smallish hoop skirt, and it was a couple of inches too long even so.  There are bra cups sewn into the bodice so if you don't fill it out, it gives you a little boost.
