OK, I made up my mind: I'll use my well-tried tunic pattern for an undergown from storm grey taffeta with a kind of kimono-like overgown from a dotted (polyester) chiffon. Well, it's not polka dots, I won't make that mistake; it's more like little round eyes in white and another colour, tightly set on a similarly grey-blue background. Very attractive. However, I want to gather the top part on the shoulders and around the hips in pleats (outward on the shoulders, inward over the hips). Did I mention it is to be slightly drop-waist? So, I want to fix the hip pleats under a kind of belt. Here comes the problem: I want to fix the belt and shoulders to the undergarment but not permanently, since the undergarment is acetate and will need ironing. Both parts need to be attached to each other since otherwise, of course, the drop waist effect won't happen the way I planned it. I'd hate to use Velcro, since it might add bulk to already bulky hips. Snap fasteners won't do either; I fear they might let me down in important moments. What else is there? Help would be greatly appreciated!
