garment display sans mannequin

[sew whatever]

If you have ceiling hanging, you could also use something like fishing wire - nearly invisible - and attach to sleeves of blouse to pull up in a dramatic way similar to puppets. I have seen stores use this method in window displays. also the skirt could just have a bit of the wire attached to one side of the hem and also pull over and up a bit to another part of the ceiling.

I suppose it also depends on how high the ceiling is.
