Salaam alaikum,
I think that depends on whose opinion you follow.
Sayid Seestani:
Contemporary Legal Rulings:
Dancing
Q178: Is it permissible for a wife to dance for her husband in order to provide him happiness and to excite him?
A: This is permissible for her. (FM, p. 436)
Q179: . . . her dancing in front of others?
A: It is not permissible for her to dance in front of any other but her husband amongst the men [rather, it is not permissible for her to dance in front of women as well]. (FM, p. 436)
Q180: . . . a man dancing in front of men or women other than his wife?
A: Likewise, it is not permissible. (FM, p. 437)
Q181: Some schools in western countries force the male and the female students to study the art of dancing. This dancing is not linked with the popular music and is not for amusement, but is part of the curriculum. Is it prohibited for the parents to grant permission to attend these lessons?
A: Yes, if it contradicts religious training, rather absolutely, based on precaution, with the supposition that the student has attained the age of puberty (bulugh). This holds except where he has a sharëi justification for studying it in the case where he is following (taqlid) the one whose ruling is that it is permissible. In that case, there is no obstacle to permit him to do this. (MMS, pp. 25-26, Q46)

558. Question: In government schools of the United Kingdom and may be some other countries also, students have to take part in dance classes to the sound of special musical tunes that synchronize the movements of the students while they are dancing.
(a) Is it permissible to attend such classes?
(

Is it obligatory on the parents to prevent their children from attending such classes if the young boy or girl is inclined towards attending them?
Answer: (a) It is not permitted, if it has any negative effect —which is quite common— on their religious upbringing. Rather, it is not permitted at all, as a matter of obligatory precaution.
(

Yes, it is obligatory. Also please refer to the answer to question no. 563 below.
559. Question: Is it permissible to learn dancing?
Answer: It is not allowed at all, as a matter of obligatory precaution.
560. Question: Is it permissible to organize dance parties where each husband dances only with his own wife to the sound of soothing musical tunes, wearing dresses that are not indecent?
Answer: It is not allowed.
561. Question: Is it permissible for women to dance in front of other women or for men to dance in front of other men in a gender-wise segregated gathering with or without music?
Answer: Dancing of women in front of women or dancing of men in front of men is problematic, as a matter of obligatory precaution, one must refrain from it. The rules governing music have already been discussed earlier.
562. Question: Is it permissible for a wife to dance for her husband with music or without music?
Answer: It is allowed as long as dancing is not accompanied with harăm music.
563. Question: Some schools in the West make it obligatory that their male and female students learn dancing. This dancing is neither accompanied by the common song, nor is it for entertainment; it is part of the educational curriculum. So, is it harăm for the parents to allow their sons and daughters to attend such classes?
Answer: Yes, if it contravenes the religious upbringing. Rather it is, based on obligatory precaution, forbidden absolutely, if the student has reached the age of maturity — except if he has a valid reason for approving of it; for example, if he follows a mujtahid who allows it. In the latter case, nothing prevents him from allowing his child to take part in [such activity].
WaSalaam, Hajar
PS: I didn't put those little sunglass things. I guess whatever is written there just makes them.
