Walking into the lingerie world for the first time can feel like learning a new language. Bodysuit, teddy, babydoll, chemise, they all sound similar but each one has a distinct shape and purpose. Here's our complete glossary of the pieces we make at Fancy Sinner, so you can shop with confidence.
 

 
A soft, unstructured bra without underwire or padding. Bralettes prioritize comfort and a natural shape. Perfect for everyday wear, lounging, and small-to-medium busts. Most pair beautifully with matching panties for a casual lingerie set.
 

 
A one-piece garment that covers the torso and snaps at the crotch. Bodysuits double as both lingerie and clothing, wear one alone for an intimate moment, or under jeans as a top. The most versatile piece in any lingerie drawer.
 

 
A teddy is a one-piece similar to a bodysuit but typically more revealing, strappy, lacy, and designed entirely for the bedroom. Think of it as a bodysuit's seductive sister.
 

 
A short, loose-fitting nightgown that flares from a fitted bust, usually ending mid-thigh. Babydolls are flirty, easy to wear, and often paired with a matching panty. Great for warm climates and women who prefer flowy over fitted.
 

 
A slim, slip-style nightgown that hangs from delicate straps. Longer than a babydoll, usually mid-thigh to knee-length, and cut close to the body. Chemises walk the line between sleepwear and lingerie.
 

 
An open-front cover piece worn over lingerie or sleepwear. Kimonos are usually shorter and lighter, robes longer and warmer. Both add a layer of drama and are excellent for the unveil moment.
 

 
A waistband with adjustable straps that hold up stockings. Worn over panties, never under. The garter belt is the most theatrical piece in the lingerie world, pure intent, no utility.
 

 
A panty cut like a short, covering more of the hip and upper thigh. Comfortable, modest, and surprisingly sexy. Pairs especially well with bralettes and bodysuits.
 

 
The three are similar but not identical. A thong has a moderate strip in the back; a G-string has a thinner string; a Brazilian sits in between with slightly more coverage than a thong but less than a regular panty.
