The pattern I used was McCalls 3830 -- if you haven't tried this already, please do! It has quickly become one of my favourites, as it's so simple but gives great results.
Please allow me to say that the steps below set out how I added lining to McCalls 3830, mainly by studying a RTW skirt that I had. This method may well not be the right or only way to achieve this, but as it worked for me, I thought I would share it in case it would be of help to someone.
Before we start, you may want to decide whether you want to make any design changes. I added a waistband by following this helpful tutorial on Coletterie here. My waistband was 2.5cm wide, but if I were to do this again, I would widen it to maybe 3cm or 3.5cm.
Now the lining. You will need slightly less lining fabric as the fashion fabric, as you won't need to cut out the waistband or the waistband facing pieces from the lining. To choose lining fabric, broadly anything that is marked as "lining" in the shop should work. However I tend to go for lightweight/thin and silky material (a faux habotai, or a lightweight satin), and if they are anti-static, that also helps. You could try and match the colours, contrast it, or insert some funky lining that no one would be expecting -- anything goes!
Part A: Making the skirt and waistband
I have not gone into that much detail here, as each skirt pattern is different, so the key is to follow the pattern instructions.
Step 1: Make darts, stitch skirt sections together, leaving room at the top of the centre back seams for the zip
Step 2: Stitch waistband sections (after interfacing them) together, leaving the centre back open. Do the same for waistband facing sections
Step 3: Attach waistband and facing right side together at the top edge
Step 4: Attach skirt to waistband with right side together
Step 5: With the waistband facing flipped out (see picture below), insert the zip ensuring that the top edge comes in slightly below the top of the waistband (rather than the facing)
After step 5, your skirt should look something like this:
Part B: Prepare the lining
Step 6: Cut the lining pieces
I used the skirt pattern pieces, without any change. I lay the pattern pieces so that the centre back seams of the skirt fall right on the selvage of the lining fabric. I often find that lining fabric frays very badly, so using the selvage would make your job a lot easier later on.
Step 7: Make tucks rather than darts in lining pieces
One thing that I noted from examining my RTW skirt was that whilst the skirt pieces had darts to fit the contour of the body, the lining pieces adjusted for this by tucks, leaving more ease and flexibility in the lining. So I did the same, and it worked. That said, I think if you made darts in the lining pieces to match the skirt pieces, that should not be an issue, either.
Step 8: Stitch lining sections together, leaving space at the top of the centre back just slightly longer than the zip length.
Part C: Attach lining to skirt
Step 9: Turn the skirt inside out, flip the waistband facing back inside the skirt (on the right side). After this you should have the top of the skirt seam which is attached to the bottom of the waistband seam at the very top, ready to also have the lining sewn to it. Pin the top of the lining to those seam allowances with wrong sides together.
When you are close to the centre back, where the seams are folded over, pin as far as you can, leaving a small gap.
Step 10: Sew as pinned, within the seam allowance. I did a 1cm seam here, but really anything within the 1.5cm seam allowance is fine, so that this new stitching won't show on the right side of the skirt.
Step 11: Hand finish the small gap close to the zipper
Step 12: Slip stitch the lining to the zipper tape, leaving extra room at the bottom for the tab
Part D: Finishing touches
Step 13: Press 1.3cm if you are using a 1.5cm seam allowances throughout (or just a slightly narrower seam than whatever you are using) down on the open edge of the waistband facing.
Step 14: Fold the waistband facing to the inside of the skirt, overlapping the folded edge over the seams (bottom of waistband and top of skirt). Pin on the right side of the skirt.
This is what it looks like on the inside:
Step 15: Stitch on the right side of the skirt. I went very slowly so that the stitching fell right into the previous stitching line so it's almost invisible
Step 16: Hem
I pinned the hemline for the skirt layer first, blind catchstitching it by hand (see Sherry's tutorial here). Then I pinned the skirt lining to be a tad shorter than the skirt itself, so it won't be seen easily when I'm wearing it (despite a part of me wanting to show off the beautiful lining!)
Can you see how the pinned lining ends slightly above the skirt hem?And there you have it! A fully lined skirt with a waistband! Give me a shout if you have any questions or would like to share your experience :)
