Hide a Pocket in a Pleat

Here are the details on the pocket from Butterick 5756, which are hidden in the side seam pleat.  

This is what it looks like inside out.

Here are the pattern pieces for the body of the skirt, they are rectangular.  The round shaping achieved at the band is through the angles of the tucks at the waistline.

We have front and back pieces here with the side seams facing each other.

As you can see, there is a tuck that bridges the side seam front and back piece.

First you add the pockets to the front and back side seam.

You join the side seam as you would any other, about 2" down from the waistband, then from the bottom opening to the hem (see pins), then around the pocket pieces.

Then you open up the seam...

And sew in your tuck

The pocket sits within the fold of the tuck, out of view.

Sorry about the black projects, they are nearly impossible to photograph.

I will say that the nice thing about these pockets is that if you have something in them, the fullness in the skirt camouflages the contents.
