@Greyhaunt: The serged edges actually were a part of the shirt design! I made the lower half from one of the sleeves, then trimmed the front with the hem of the shirt. The top has a lining made from the same shirt that the underskirt is made from, and there are 3 tiny snaps holding the top closed, hidden inside the bodice.
@fleacollar999: The little studs on the collar are actually from a different old shirt, but you can find similar ones in the scrapbooking department. The have a whole ton of different shape and color studs and eyelets.

Those little gold ones are 1/8" or 3.1mm so roughly the same size as the largest of the eyelets you can get on the VolksUSA site, (they carry 2, 2.5, and 3mm eyelets) Incidentally, I just ordered some of the 2mm ones in gold and silver, so I'll do a comparison of the two, at some point. The gold flowers are actually bell-caps that I bought at a craft store years ago.
