Yem

Yem refers to an ancient Vietnamese bodice used primarily as an undergarment that was once worn by Vietnamese women across all classes. There exists a modern variant called "áo yem", but the historical garment was simply called "yếm". It is a simple garment with many variations from its basic form, which is a simple, usually diamond or square-cut piece of cloth draped over a woman's chest with strings to tie at the neck and back.

Ribbon Corset

The ribbon corset is made of pieces of ribbon, as opposed to fabric. In 1901, a simple pattern of silk ribbon, two bones, and a busk was available, allowing women to construct their own ribbon corsets.

A pseudo-ribbon corset looks like a ribbon corset but is made from cut cloth instead of ribbons. The outside seam of the cut cloth is sewn fine, while the tight inside seam is sewn plain and curved.

Waist Cincher

A waist cincher (sometimes referred to as a Waspie) is a belt worn around the waist to make the wearer's waist physically smaller, or to create the illusion of being smaller. Today Waist cinchers and Waspies from the 1980s are a type of wide, laced belts with elastic fabric and soft plastic stiffeners.

Pettipants

Pettipants are a type of lingerie worn by women. The name is probably derived from a portmanteau of the French word petit ("small"), the spelling "petti" coming more cirectly from "petticoat," and the English word pants. Pettipants are similar to long shorts, though they may be made from material such as cotton and lace, and usually have ruffles down each leg. They are available in different lengths up to knee length.

When pettipants were fashionable, they were usually worn under skirts, dresses, culottes, or walking shorts for modesty or comfort. However, they are not considered a modern or popular style; currently they are most likely to be worn by square dancers or persons involved in historical reenactment. Unlike other types of underwear, pettipants will not ride up and eliminate hot-weather chafing.

Petticoat

A petticoat or underskirt is an article of clothing for women; specifically an undergarment to be worn under a skirt or a dress. The petticoat is a separate garment hanging from the waist (unlike the chemise).

In historical contexts (sixteenth to mid-nineteenth centuries), petticoat refers to any separate skirt worn with a gown, bedgown, bodice or jacket. These petticoats are not strictly speaking underwear as they were made to be seen.in both historical and modern contexts, petticoat refers to skirt-like undergarments worn for warmth or to give the skirt or dress the desired fashionable shape. In this context a petticoat may be called a waist slip or underskirt (UK) or half slip (US), with petticoat restricted to extremely full garments. Petticoat can also refer to a full-length slip in the UK, although this usage is somewhat old-fashioned.Petticoat is the standard name in English for any underskirt worn as part of non-Western clothing, as with the sari.
