I adapted the pants pattern from my Pants, Skirt and T-shirt pattern for Twinkle to make the tights.
Make a copy of the pants pattern. Cut off the side seam allowances and the fold line for the elastic casing. Fold in the  side hem tabs at the bottom of the leg pattern.

For top and tights use a ladies thin black sock. Use black elastic for the top’s straps.

Cut the tights from the foot and toe end of the sock. (I took a picture with a pink sock, because I had already used all my black socks.)

Follow the pants pattern directions to make the tights.  I sewed the elastic casing at the waist by hand, because the sewing machine tended to stretch the sock fabric too much. After inserting the elastic use a quarter inch (6 mm) seam with a zigzag stitch to sew the back seam and the inside of the legs. Sew across the bottom of each pant leg, so that the doll’s feet stay inside the tights.

The doll’s top is made from the top of the sock, after the tights have been cut out. Try the sock top on the doll, by having her “step into” the sock top. The cut end of the sock should be pulled up to just below her shoulders. The finished end of the sock should be at her waist. Trim the cut edge of the sock to shape it like a doll’s top. Remember to leave enough of the trimmed sock fabric to add a hem.

I had to make a seam down the back of the top to make it small enough to fit the doll.

Hem the shoulder/neck/arm opening by hand and add black elastic at the shoulders.

Here is the doll in her tights and top:

For free tips for making an elastic casing download my free Tools, Tips, and Techniques booklet and look on page 9 of the booklet.

You can purchase a download of my pattern Pants, Skirt and T-shirt from the small doll section of my Pattern page. It is the fifth pattern in that section.

If you are only interested in AG mini dolls, the pattern is also in my book, Sewing for Mini Dolls. If you only want mini doll patterns, I think that the book is the best buy. You can find out how to order it from My Books page.

Next week I will show ;you how to make a dance skirt to complete the outfit.
