Having sewn a couple of vintage-y halter tops of late, I found I need to pad the cups out a bit; there are several patterns online for bra pads, but to get the slightly conical 1950s shape, I have devised my own pattern which is mine, and which I have dubbed the "Titrahedron."
From the cloth of your choice (satin is nice) cut an equilateral triangle, three to four inches along each side (depending on the desired size). Right sides together (if applicable), fold the three corners up to meet each other and sew three short seams. Obviously you will not do the last seam until you have turned the shape right-side out and stuffed it. Repeat for second pad. Place inside bra or halter top, one corner pointing into the depths of each cup, and secure in place with a few stitches.
