How married cross-dressers are accepted by their wives varies greatly and an acceptance and understanding will depend on a great many things, such as the cross-dressers ability to express his need, how much he is willing to compromise, meaning whether he will keep his predilection hidden from society, and on the wife's level of security and mental maturity.
The situation may be greatly affected by how she learns of her husband's need, and the effect of having it explained to her beforehand will most likely be very different to coming home and finding him wearing her clothes, or even worse coming across him in the street wearing their daughter's clothes and makeup.
Some wives are able to fully accept the newly discovered situation and might even allow their husbands to appear in drag shows and even attend and applaud, whilst in many cases the discovery might lead to a divorce.
