There are 2 areas where SS seems to work:
1) SS appears to be better for slimmer guys who are still built like they play a sport. I think chocsosa said once he was a LeBron size which means tall, with broad shoulders and chest, but still tapered to his waist. I am a 6' version of that (minus the barrel chest, unfortunately). I'm built like a cross country runner and I have played soccer my whole life. I can wear a 38-40 jacket then drop to a 32 waist on the pant.
2) The company is Dutch and caters to young people, therefore some of the styling is more fashion forward than say Brooks Brothers. Higher button stances and higher notches is one of those. So if you want a Euro cut then it may be an option. If you want fuller cut, classic American style then probably not.
Personally, I like the higher notch because I think it looks sleeker compared to the below-your-tie-knot notches of the 80s and 90s. And on the fit, for a guy like me, I have found their jackets have a bigger drop and therefore need less alterations through the body.
There will always be outliers. SS has 3 different factories, and you're bound to have some discrepancies between them. Myself as an example, I didn't touch the jacket on the first Napoli suit I bought, then 6 months later I get a 2nd and I had to do some tailoring. Some areas were identical - shoulders, sleeves, length - but the body was slightly different. So it goes.
So to quad's point above, yeah it's not going to work for everyone. A colleague of mine who is of similar build but paunchier in the stomach had a J Press blazer. Fit him well. I put it on and thought it was like wearing a box. What has been good about Style Forum for me is that I can see people in other brands and start to get a sense of what may or may not work. Saves me time and shipping fees when looking for suits.
I agree Cousin..Im not a fan of the lower gorge thing. While I respect that it has it's place in the traditional sense of tailoring, its not really my thing. And it does have a more aggressive taper than a brook brothers but not tight. For instance I saw a brooks brothers suit the other day at Nordy Rack.. decent fabric in the fitz cut in my size.. I would to have done too much work (take in waist, lengthen sleeves, taper sleeves a little, take in pants, taper pant legs, hem pants, and add sleeve buttons). Like I said too much work. I have not had to do half that on both suits combined..and I believe they are both half canvassed..on a side note I did pick up a fly Zegna Suit in the milano cut.. my third Zegna suit in a trefeo fabric..had to do minimal work and it looks awesome.. light blueish grayish fabric with pinstripes and 20% silk... straight money! lol
