Front View: The front has a buttoned down bodice. There are two buttons going down the bodice, but then at the empire waist, there are two more buttons to hold the dress together. There's also a separate collar that comes out at the neckline.
Details of the collar: There's a lot of fine white embroidery on the collar. The edge is not a straight edge, but has a fancy "zig zag" detailed edge. This picture is also a screenshot from a meal time at Longbourn.
