I am by no means an expert but to my eye the db does not look good on you. Neither does the wide lapels and large cuffs.
I think you could get away with narrow lapels and would do better with a 2b, high gorge, and no cuffs. I think your view of the rules is really skewing your overall look and you should take more chances.
If you got that rig made up by a tailor, I am interested in what direction they would have gone without your input.
well... foo might actually be 1.5m tall ... and he can't change that....
that being said
i don't think this DB coat does anything to help with the height challenge
i don't know if it's the cut or the buttons or what... but just doesn't help to create an elongated silhouette
probably better to stick with a SB?
Large cuffs shorten the legs whilst the 4-1 elongates the body making him look more childlike. The fit of the suit is excellent, just the style totally not right for his stature.
