dress code for a hot wife

Hey all, we have been dabbling in this lifestyle for a little over a year now and we want to make a solid go of it. No more messing around, we want to do it right, so “R” and myself have been talking to a man who has had some experience with this lifestyle and he wants to help us, he and my wife get on very well and the sex they have is explosive so they want something a little more permanent.
Where do you start….. lol, he want us to act and be like the genuine article(can’t say that i blame him i’m loving this) right down to the way R and I act, Dress code, the flirting, real hot wife stuff in fact we want to integrate him into our family, we have small children that we have to consider and if we go down the life style road properly we need to strategize. I have done some research and have found “Cuckold Marriage Info” (written by Luvr) I like his idea’s on Integration,It makes good sense to be up front with the family, (we have been hiding it for the past year and it’s not very satisfactory) obviously the children will “NOT” be involved in any activity that would be considered lewd or in bad taste, but there is no reason why they should not meet and and welcome him into the family as a very good friend(special friend) of their Mum and Dad.
How should the hot wife dress for the times the boyfriend comes over for dinner when the kids are there, bare in mind she is going to be a hot wife and should dress the part (not going to overboard unless the kids are away for the night.. 3yo/ 4yo boy /girl by the way) and nudity is not a stranger in our house, it is acceptable to walk from the shower and bathroom to all parts of the house, we hide none of that.
So if any of you people out the can give us an idea of what a hot wife should wear on a home date or a out date where the children will see her getting ready and see that I am perfectly ok with and totally support her in I would be very grateful, maybe if any of you good people out there have some pics of some nice hot wife evening wear that would be fantastic.
