I totally agree views of marena..... mostly it is a symbolic thing and association of night wear with your first night is pretty strong.....
there has to be balance between how much you wanna please and how comfortable you are.....like there are still many things that we do not know about hubby at that time..and being too sensual could backfire too...but if there has been some communication between hubby and wife before getting married then do inquire about his likes and dislikes and go from there without getting too much uncomfortable....
If you are not sure have sumthing which gives a hint :) yet is classy, like sumthing with deep back and side slits riding high.... in that way, you would have flexibility to change "his views" by changing your sitting postures etc according to the "atmosphere" in your room.......
