I'm a former cosplayer, so the prospect of using my sewing machine for something original, or outside the realm of anime/manga is pretty foreign to me. Thus, my first In Real Life project began with..
a calvin klein pillow
an extra large men's shirt
..and a vintage slip.
i almost like it better without the straps, but i'm still not sure so i sewed them on with a fairly loose, wide stitch. same goes for the ribbon, because i didn't actually have any genuine ribbon on me - i used the straps of the slip as a temporary replacement..
