for myaku, if you go to joannes or fabric stores u can find pink PVC. i highyl suggest you try to follow teh pattern of the corest you got for TSumi but alter it. i used metal boning, my myaku corset is far from perfect but i made a new one.*never had time to re-wear it* Myaku was my first costume ( i made it when i was 14 *EE)
anyways..i really suggest u make it so it zips up or ties up the back. i made the mistake of making everything in the FRONT..
for tubes if u can't find them *wink wink* (secret: look in toy stores) ^^b (ahem) you might have to "drain" some of them
