Not Your Granny's Panties: Tap Pants and French Knickers

My entry for the Historical Sew Monthly Challenge #3 Stashbusting is a pair of pink satin tap pants. But what are tap pants?

Tap pants, also known as French knickers or step-ins, are a style of loosely-fitted underwear that was popular from the 1920s to the 1950s. They are characterized by a fitted waistband and flared leg. They were usually made of silk satin or silk charmeuse in soft, pale, feminine colors like pink, beige, and a range of pastels, and were frequently trimmed with lace or decorated with lace appliques.

Here are some examples of tap pants/French knickers from the 20th century:

So what's the big deal with tap pants?
Besides adding the extra touch to your vintage outfit, tap pants are great to wear with modern clothes. Because most tap pants are cut on the bias, they cling to the curves of your body and can be very flattering. Tap pants are perfect to wear underneath dresses, skirts, and certain trousers because they won't give you Visible Panty Line (VPL). You can wear a garter belt underneath tap pants to make using the bathroom easier. Tap pants are comfortable, practical and sexy!

Tap pants sewing patterns
Because of the rarity and fragility of vintage items, I think the best option is to make your own tap pants. They take very little material to make and require basic-intermediate level sewing skills, like french seams, bias bindings, elastic casings, and plackets. There is quite a variety of reproduction tap pants patterns available on the market today.
