I recently got model 114 in the 609 colour and found them great under grey flanel, combined with a blue sports coat. In my view they're formal enough, but can also be worn under jeans for instance; something I won't do with my black cap toes.
I have been told that the 358 has een little more room in the front than the 348. I have 2 pairs of monks in 358 and 4 pairs 348, all with laces. Reckon that gives a different 'feel' as well.
I tend to agree that the picture indicates the opposite..
Ordered a shirt 2 weeks ago when I was in Florence. The shirt will be sent over to me by mid September due vacation. I have ordered Thomas Mason fabric, choice was more than abundant. Looking forward receiving the shirt, upon which will post some pics.
