While waiting my turn in 'the Que' for my new Newsome tank I'm revisiting jacket ideas.

I have a Saxon style sport coat that has no buttons nor buttonholes. It looks quite nice, traditional cut but sans buttons and holes, a very modern looking jacket. Do you think a 'Wallace' style jacket would look good sans buttons?

I'm also looking at jackets with mandarin collars: http://www.makeyourownjeans.com/inde...5446523c0a5f60

Can a single style of cut [IE Wallace, or Nehru] work with only a change in the fabric? Example: we know an Argyle can work for day wear all the way up to formal depending on weather it is tweed or black barethea wool. Do you think the same would hold true for a jacket with a different cut?

Taking the Nehru as an example: a casual jacket in say corduroy, more dressy in say wool tweed, dressier still in black wool, and most dressy in velvet. Would the same cut [Nehru] work for for all the levels of formality?

Opinions with explanations for your reasoning appreciated. Thanks.

P.S. I'm not looking for a traditional vs. modern discussion. Just cut and material comparisons.
