Sewing help needing-lining for crepe back satin

[MaitlandGirl]

For some unknown reason I've told DD2 I'll make her dress for her school formal (!) I can sew and follow a pattern but just can't work this one out.

I'm using a crepe back satin with an organza overlay. The satin forms the lining for the skirt but I think it needs an additional lining for the bodice.

What would be the best fabric to use?

The pattern is Mccalls M6647.

Thanks :)

The easiest thing to do would be to self line with the same fabric, if you have enough. Other than that a simple polyester lining in a similar colour should do the trick.

Thank you :) I've been overthinking it so much that it never occurred to me to self line or use polyester!
