The variety of lingerie — and the names — from Butterick’s 1924 underwear patterns is amazing to me. It’s a specialized area that doesn’t really make me want to hit the reference books. However, for those of you who love or collect vintage undies, here are some images and pattern descriptions from 1924 and 1925.

The two garments on the right are called “combinations;” The one with birds is Butterick 5030; the one on the far right (“drawer skirt combination”) is Butterick 5050. Delineator, February 1924.

A closer look at combination 5030 and drawer skirt combination 5050. No. 5030 seems to form into legs, but in fact the front and back hems are connected with a strip of fabric.

The back view implies that 5050 has a crotch strap running from front to back [and closed with buttons]. The text doesn’t really explain how number 5050 is constructed. “Tub” means “washable.” 5030 is a “dainty step-in combination chemise and drawers.”

These two patterns were illustrated repeatedly, but not together, with varied descriptions. I arbitrarily referred to this pale green one-piece as a “teddie” in a previous post, but I’m no longer sure that’s the correct term. It might be “combinations” or a “step-in” chemise. [See comments.]

This pale green, tucked teddy [or step-ins? or combinations? ] has a crotch strap, barely visible. It stops at the edge of the netting lace. You can see a straight line of stitching where it attaches to the garment, about an inch or so above the lace trim.

Vintage step-ins; the crotch has no buttons, the sides are open below the waist, and they would not be easy to step into, because your hips would have to fit through the waist — or, rather, the waist has to be as big as your hips.

Detail of leg on vintage combination step-ins. It would not be easy to answer the call of nature while wearing these.

Butterick “Step-in” 4112 and “Envelope Chemise” 5059, pictured in Delineator, June 1924. You can see the button crotch in both of these. But how does a “combination” differ from a “step-in?” Or a “step-in combination” as it says here?
The very low crotch looks uncomfortable to a woman who grew up wearing knitted briefs, but there was probably a notion that “the parts need airing,” as was sometimes claimed by wearers of kilts.

Butterick “cami-knickers” 5124 with “envelope chemise” 5059. Delineator, April 1924.
Munsingwear offered this unfussy, step-in version of a “woven union suit with closed gore, step-in style.”

Ad for Munsingwear knitted underwear for women; Delineator, June 1924. If the crotch strap was close to the hem, that “wide opening at the side” [see below] would be needed.
Below, a pair of “knickers” held by a young woman wearing an “envelope chemise.”

The model wearing “envelope chemise” 4137 is holding a pair of “knickers,” pattern 3197. In the U.S., “Knickers” sometimes referred to undergarments in January 1924, and still does in England. Delineator, January 1924. [And Delineator was published in England as well as in the U.S.]

Butterick knickers pattern 6194 was brand new in August of 1925 — and these knickers are definitely underwear.
But, to add to my confusion, Butterick offered knicker pattern 3496 as outdoor wear, also in the summer of 1925.

The number series suggests knicker pattern 3496 was issued back in 1922 or 1923 and still popular in 1925.

Knickers? Bloomers? Drawers?

Butterick pattern 4974, for step-in “Drawers” was probably issued in 1923 or early 1924. These have elastic in the waist, making them easy to step into and draw up.

Butterick “step-in drawers” pattern 5564, from October 1924. “Under the new narrow dresses you should wear lingerie cut on correspondingly narrow lines.”
This set (“chemise and drawers”) was featured in June, 1924.

A “French chemise” and one-piece step-in drawers, Butterick 3826, illustrated in June 1924. I’m guessing that the pattern contained a camisole-and-drawers version and an all-in-one version as shown at right. “Width at bottom of each leg 30 inches.”

This vintage step-in [1/17/18 edit: Combination] chemise would look different on a human body. This silky beauty has no waist seam. It does have a button crotch.

“Drawer-skirt combination” (5050, at left,) camisole 4957, and envelope chemise 5059. Delineator, May 1924.
This lovely vintage set of camisole and drawers shows its button crotch clearly:

This vintage set — I love the contrasting lace and embroidery color — has a separate camisole and [not step-in] drawers. Since the waist is not elastic, the “drawers” need to have a button crotch.

Detail from Royal Society ad, November 1924. The camisole costs $1.25 and the drawers [?] cost $1.50.

Butterick 4974 was called ” step-in drawers” in January 1924. They have an elastic waist, so they might not need a button-crotch. For hips 35″ to 52.”

A new set of step-in drawers “in a skirt effect” is illustrated in October, 1924: Butterick pattern 5565. These would need a strap-type crotch of some kind. [They don’t have separate legs, so why are they called “drawers?”]

Bloomers, Butterick 5705; Delineator, March 1925. To read about boneless corselettes, click here.
But bloomers, like knickers, could also be outerwear:

Butterick “combination” 5030 (again) and bloomers for a little girl [or girls 2 to 16 years!] Butterick 5065. Delineator, March 1924. These bloomers are attached to an underbodice, very practical for the years when little girls have tummies bigger than their hips. [I remember needing suspenders on my skirts in first grade….]

Often, “bloomers” were intended to be seen, and were worn by almost all girls as part of their gym suits, or for any active pursuits. The middy blouse would cover the underbodice:

Middy blouse 3849 was a classic. I have photos of my aunt and friends graduating from high school wearing a middy-blouse-plus-white-skirt uniform in 1917. Gym bloomers (“for girls or misses 2 to 18”) were very full, often pleated. Delineator, February 1924. The Vintage Traveler shared a whole middy catalog from the 1920’s here.
Did I learn anything from this adventure in undergarment nomenclature? Only to avoid making absolute pronouncements about bloomers, knickers, drawers, teddies, chemises, camisoles, combinations, and step-ins! [Please see helpful comment from thevintagetraveler!]
