The is a beautiful hat. Is peach or salmon in color. Has stick pins as babies breath and rolled satin flowers. I cannot tell what size the hole opening would be for this hat by the outside dimensions of the hat are approximately 6 inches (just diameter of hat rim). Is framed in a deep shadow box frame. Somebody loved this hat! The outside dimensions of frame is 19 x 19 inches and is 4 3/8 deep. The inside of the glass needs cleaned. A sliver of the frame is missing as shown. Is just a gorgeous display of a gorgeous hat.
