Compression bras, such as sports bras, push against and minimize breast movement, whereas encapsulation bras have cups for support. Breast support may be built into some swimsuits, camisoles and dresses. Bras come in a variety of styles, including backless, balconette, convertible, shelf, full cup, demi-cup, minimizing, padded, plunge, posture, push-up, racerback, sheer, strapless, T-shirt, underwire,
Shelf in the Room features a vocal distortion during the chorus. Lyrically, the song often refers to a key and tends to vaguely describe emotional stability and isolation. The shelf is considered a means of security with the chorus line, "The shelf in the room has been so true/I can hide in the shelf in the room." It is also described as "holding me, and letting me stay." These themes are illustrated through the song's music video. The video for "Shelf in the Room", directed by Sean Mullens, bears the rural and color aesthetics depicted in the album art of "Days of the New".
