As an update, I only have to do a little bit of resizing (I forgot seam allowance on the white when I inserted it to the black, so it's about 3 in. too small,

) and then hem the bottom and add the velvet, but mine's nearly done - I ended up using a satin (I wanted something matte, but it was $3 a yd. and I had to buy the material myself, so I compromised, lol). I might end up adding straps so that I can just wear a bra and cami and not have to buy a new strapless bra, because my one from Sadie's recently crapped out on me.... Well, off to work on it. Anyone making something for homecoming - good luck!
