I made a lingerie set with this blue lace bra. I used Pin-up Girls Alyssa as a starting point but constructed the band the same way MakeBra does e.g. in one piece. Well, to add the scalloped edges to the wings I did need to make a centre front seam to the lace but still, I didn't have any side seams. I supported my lace with powernet and an extra stabilizer behind the centre front to keep the cups in place.
I left the scalloped edge to decorate the cups and added more character with a thin piece of black stretch lace. I finished the side of the cup with foe instead of using elastic and sewed the straps to the ends of the elastic.
I covered my front straps with stretch lace and added some bows and a little charm as a decoration.
My blog post contains a lot of details and pictures on how I constructed this bra. You can find it here.
This is how I supported y stretch lace. There is black powernet and a special stabilizer fabric behind the centre front (turned up in the image).
