So much to read...

I am getting around to buying a suit for myself.
After trips to Subang Parade and Pyramid and trying ALL the suits in the dept stall, I find I apparently have weird shoulders. Only 2 brands out of the dozen there ngam my cut, that also not fitting very well.

Anyway, I dropped by de-catano in Summit (Point B also cannot find) and they quoted me to do a 2 piece for about below 1.5k. The 3 piece was almost 2k so I declined the waistcoat.

Getting to the point of this post, he was showing me synthetics both lycra and rayon. Black and slightly stretchable. As I understand, pretty much everyone says to go for wool. Are those material he recommended a bad choice or is wool another price level altogether? (I forgot to ask him)
