While I agree that men should be very clear with their wives as to what is acceptable and what is not, the excuse that the husband wants her to look good is not an excuse for her to dress inappropriately and it cannot, therefore, shift the blame to the husband if they both know better.
In other words, if both know very well that it is wrong to behave and dress like a zona, then she can still dress differently at home than in public. But in public (and in private, too, for that matter), her obligation is to dress like a bas melech whose kavod is reflected from within, no matter what anyone else thinks or feels about it.
