Forced dressing is a BDSM practice where a dominant may force their submissive to dress in a certain manner. They may do it privately for their own enjoyment or publicly. Generally, forced dressing is a form of psychological play as the purpose is often humiliation.
More About Forced Dressing
Forced dressing, as like any other "forced" BDSM activity, will generally be based on negotiations and agreements that the dominant and submissive have discussed in advance. For some, humiliation is a fetish in and of itself. For others the particular form of dress will indicate the fetish at play. Some may enjoy both the mode of dress and the humiliation.
It is important to remember that "forced" BDSM activities still must be consensual.
