Dress codes in dance class are

1) necessary in early stages of ballet training.

2) a formality in exam classes.

3) not enforced in most dance companies.

4) a way of teaching students discipline in their attitude towards dance.

5) helpful in removing distractions for ballet teachers in class.

Examplification:

1) In order to be able to see the dancer's positioning, the teacher must be able to see not only their body, but also the way their muscles work. This is why beginners of classical ballet are often advised against wearing tights which, even though they are very thin, can be a barrier in observing the dancer's technique.

2) By having a dress code in exam classes, students are encouraged to step up to the occasion not only in performance but also in acknowledging it as a formal event.

3) Dance companies do not enforce dress codes mostly because of the preference of each dancer for certain types of warm-up clothing. Furthermore, the lack of a dress code gives dancers the opportunity to develop their individuality and grow in different directions.

4) By following the rules of dress codes, dance students are taught to take their dance genre seriously and as a discipline as well as an art form.

5) Teachers can be easily distracted by baggy clothing, seeing that these disable them from seeing mistakes in a student's technique. When the whole class looks the same, a teacher can focus on pinpointing mistakes more easily, thus giving him or her the ability to correct more students.

Comparison:

Dress code: dancers are equal, teachers are able to correct them, there is a sense of discipline in the studio.

No dress code: dancers are individualized, teachers may find difficulties in correcting technique.

Casualty:

Dress codes in dance classes, especially classical ballet classes, are something on which everybody has different views on. Most prestigious schools and studios require their students/dancers to dress a certain way, while there are those which do not have special requirements beyond the usual leotard, tights and ballet slippers. However, in professional companies, these dress codes are rarely enforced, which may be seen as wrong in the way that the ballet masters are restricted in their ability to improve a dancer's technique by corrections.

Effects:

Dress codes in ballet schools will certainly lead to dancers attempting to stand out in class in more subtle ways such as wearing jewelry (if allowed), head-wear, and makeup.
