Go Ahead and Have a Hissy Fit
If you cannot seem to find the retro look you have been looking for in your size then Etsy is definitely a good spot to look. The online shop Hissy Fit (I think it was named after me) has about 45 items available in sizes 1x to 4x and they are all convenient divided by size. Most of the offerings are dresses but there are a few skirts too. My favorites shown here range in price from $47 to $105 (I wish she did not cut the heads off her models).
The dresses are made in Australia but she has reasonable shipping to the U.S. and Canada.

That pink floral dress is cute especially with the blue tights.
