Butterick skirt 1480 was first illustrated in June, 1927, with a blouse/step-in combination (No. 1493) and a cardigan jacket (No. 1367.) Delineator.
This very simple wrap skirt pattern first appeared in 1927. Surprisingly, it was still being featured — in a much longer version — in December of 1930. It had survived a major change in fashion. There is only one copy in the Commercial Pattern Archive, so I can’t be sure if the pattern was produced in a longer version after 1929, but it is certainly longer in illustrations from 1930.

Buttrick wrap skirt No. 1480 barely covered the knee in summer, 1927.
A 1928 version — still short, can be seen here. A different combination blouse and step-in — copied from Vionnet — appeared in Butterick’s Delineator in 1929. [And it had a zipper!]
The “one-piece wrap-around straight skirt” really is simple, with just four parts: Front belt [the front waistband,] back belt [waistband,] skirt, and an optional pocket. (The dressmaker would need to figure out linings, facings, etc. )

Here is the same wrap skirt illustrated in July 1927 — this time with a sporty striped jacket:

Upper left: wrap skirt 1480 again. September 1927. These three styles are unmistakably “Twenties.”

This time, skirt 1480 was shown with a jacket-like ; the blouse opening lines up with the flap on the skirt.
By Fall of 1929 the new, longer skirt had been introduced.

Butterick wrap skirt 1480 is shown with overblouse 2802 (still in Twenties’ style) and a flared coat (Butterick 2794.)

The skirt covers the knees completely. (September, 1929.) This coat is about the length that some dresses were just 18 months earlier.
Notice how quickly the longer skirt took hold — there’s a big difference in patterns from September 1929 — above — and October 1929, below:
In October of 1929, skirt 1480 was shown with overblouse tucked in, in the alternate view.

In 1927, the wrap skirt was described as “mounted on a belt that rests just above the hipbone.” In 1930 it “fits snugly over the hips at a high waistline.” To me, this sounds like two ways of saying the same thing — if the pattern was really much changed, it would have been reissued with a new number.
In her History of the Paper Pattern Industry, Joy Spanabel Emery showed two pattern envelopes of Simplicity 1866 — “first issued in 1946 and reissued in 1947 with a longer skirt. (The fastest and simplest solution was to lengthen existing skirt patterns by three inches.)” [Pg. 164.]
A few months later, by 1930, skirts were well below the knee, and ways to stretch your wardrobe were… creative.

(There are four patterns listed: Jacket 2993 (left,) coat 2812 (over her arm) frock or blouse 3002 (center and right, and skirt 1480 (shown three times.)
By Fall of 1930, most traces of the Nineteen Twenties’ look are gone. Skirts are mid-calf; belts approach the natural waist.

Butterick dresses from October 1930. The tunic second from left (3471) is a transitional style, like the tunics [below] that appeared at the end of the Tubular Twenties. Under the 1930 tunic: wrap skirt 1480.

Yes, that October 1930 tunic was worn over 1920’s wrap skirt 1480. So was this one, from December of 1930.

Stylistically, the “Twenties” are over.
Why a wrap skirt should be the choice for wearing under a tunic (or over a dress!) is a mystery to me. But, as seen, easy wrap skirt 1480 survived a fashion earthquake.
P.S. Looking at the tunic dresses of 1924 and 1930 I was shocked to realize how little time elapsed between them. The short-skirted Twenties were short indeed.
