Once you have attached the pockets, you can sew the facings to the front pieces. 
Next, iron the hem upwards. Fold the facing inside out ( right sides facing). 
What you see here is the facing that's on the front piece ( you can see a bit of the pocket at the top left). The yellow line is the one you need to sew now. It starts exactly at the fold of the hem and tapers to 1cm from the edge. Do not sew all the way to the end of the facing, otherwise you won't be able to attach the lining. 
When you fold the whole thing back over, it will look like this when finished.
Have lots of fun with it.
