"Rules" for dressing up

[Chef]

I agree about the wing collars. I think they look really weird, and much prefer the look of lay down collars. One of the reasons I started this whole thread was to clarify that it is not just "okay" to wear a lay down up through black tie, but that it is actually "proper".

If lay down collars were good enough for all the James Bond films and Old Blue eyes could you possibly need any other direction

I like the look of the laydown or spread collar tux shirt, I think it goes very well with an Argyll jacket.
