This stunning red dress comes from S1.Ep3 when Evelyn and Mr. Pamuk come to stay. I choose the name from a quote that Matthew says to Evelyn when Mary passes these two suitors over for the exotic foreigner. "We should brush up on our powers of fascination."
This dress features a rather simply shaped sleeveless red underdress with a floral embroidered sheer over layer. It looks kind of sparkley in this photo so maybe there are metalic threads or beads on the top layer. It also has the characteristic between empire and natural waist waistline of the period with a wide red sash. The fun red sleeves are made from a darker sheer red fabric.
This full length shot shows that the sheer overlay goes only part way down the dress and has the same pretty scalloped edge on the bottom as on the neckline. It also looks like there may be a small train. And I do believe the sheer layer is a smidge longer in the back than in the front.
Here's a close up of the front and a bit of the back reflected in the mirror. Looks like the sash may have a bow in the back.
Mary styles it with a midsized necklace with dark (red?) stones and elbow length evening gloves.
I really love this dress! If I do ever get around to making an evening gown for Costume College, this one is a possibility.
