In this case, the sound reaches the center of the stadium and the center of the stands at the same moment provided the band members are not correcting for each other. Uniforms Nearly all marching band personnel wear some kind of uniform. Military-style uniforms are most common, but there are bands that use everything from matching T-shirts and shorts to formal wear. The school or organization's name, symbol, or colors are commonly applied to uniforms. Uniforms may also have substantially different colors on the front and back, so if band members turn suddenly (flank), the audience sees a striking change of color. Band members at many Ivy League schools wear a jacket and tie while performing. The Southern Methodist University band wear a different combination of jackets, vests, ties, shirts, and pants for each half (changing before halftime) of each game and no clothing or uniform combinations are repeated during the marching season. The Alma College Kiltie Marching Band is famous for wearing kilts made of the official Alma College tartan. The components of a band uniform are numerous.

The USC Spirit of Troy Marching Band and Troy University's Sound of the South Marching Band wear traditional Trojan helmets. It is also common for band uniforms to have a stripe down the leg and light-colored shoes, or spats over dark shoes to emphasize the movement of the legs while marching. Similarly, uniforms may feature additional components which highlight movement of the upper body, such as the "wings" worn by the University of Minnesota's marching band to highlight flanking movements on the field. Competitive bands, however, many times opt for matching uniforms, especially pants and shoes (usually white or black) to hide the visual effect of members who are out of step as seen from a distance. Occasionally, a band forgoes traditional uniforms in favor of costumes that fit the theme of its field show. The costumes may or may not be uniform throughout the band. This kind of specialized uniform change is usually confined to competitive marching bands. Drum Majors, the field commanders and band directors, usually do not wear the regular band uniform, to better distinguish them from the rest of the band. Some wear more formal outfits or costumes that match the
