Buy a traditional bodice, basque and skirt if you'll be dancing in a formal performance. The tutu's bodice will often be separate from the skirt and feature up to eight panels of fabric with boning in some of the seams for added support. Fasten it with a series of hook and eyes for a secure and proper fit. Tutu skirts will feature a tight-fitting band called a "basque" that will attach to the bodice (see Resources).
Choose a "classic" tutu for a traditional "ballet look." The short skirt will either be completely flat and wide with wire hooping in the ruffles to keep it stiff or it will be softer and fluffier with additional rows of ruffles and no hooping to create a "powderpuff" appearance. The skirt should jut out from the hips to show off more of your leg movements.
Create a more flowing profile with a "romantic" tutu that features up to five layers of tulle. Opt for a knee- or ankle-length skirt depending on your instructor's wishes and either wear it at the waist or choose a dropped-waist style with a basque. The longer length is flattering for taller dancers and may also make it easier to dance with a partner since a classic tutu's width may put awkward distance between you.
Wear a "bell" tutu as a compromise between the other two styles. This style should be worn hanging from the waist or hip and will be shorter and fuller than the romantic style, but longer and less stiff than the classic.
Coordinate the color of the tutu with the tights and leotard if you're buying separate pieces for a less formal ballet class. Some instructors and students prefer a tone-on-tone look with a pink outfit and matching tutu, for example, while others opt for a more dramatic look with a black leotard, pink tights and a pink tutu. Skirts are typically available in wrap or elastic-waist styles in a variety of colors and weights.
