Also, don't fret about matching lining colours. If your main fabric is translucent, lining colour matters, but otherwise it's for your eyes only.
Interfacing is for reinforcement, and can be ANYTHING. Like most, for years I was brainwashed into thinking it had to be vilene or some other specific interfacing. Now I use anything I have around, and match the weight to the fabric and finished effect [ie do I want s soft collar, or a very structured one, etc.]
