I have a black hopsack blazer that I have retired since joining this forum. Maybe I should get it back out again.
I do like the idea of a DB or SB peak lapel jacket though. Anyone have any recommendations for about $500?

What about footwear? I guess the idea is to avoid typical business shoes. Also, is there some kind of rule about no wing-tips at night? Is black the preferred color here or does brown work as well.
I have been considering getting these shoes (http://www.kentwang.com/shoes/benchgrade-plaintoe-balmoral.html) for use with formal evening wear, and am wondering if they are suitable for non-formal evening wear as well.
Also, what about shoes like this: http://www.allenedmonds.com/aeonline/producti_SF4135_1_40000000001_-1
Since they are semi-brogues, are they not suitable for evening? Should I stick to only wearing those in very casual situations, like jeans and no jacket?
Thanks. I don't think I'm ready for the Belgian loafers. At least I'll be able to use the KW for something besides black tie. Apparently they aren't business-appropriate.
