I don't have this model in my store, so I can't know with a hundred procent certaincy what model it is - also because all those photos are retouched digitally, and clothes are pinned etc, so sometimes a regular fit suit looks exactly the same as a extra slim fit on a online website (yes, it is dumb!)
I'd say there's a 80% chance of this being a Huston Gander model though, It's a slim cut blazer, but tailored not to be too fitted. Slim-cut, mid-rise trousers with unfinished hems. Model is wearing an IT 48, and he's somewhere around 6'1. The hem width is 7.7" / 19.5 cm.. This is a wool suit with silk, which will have a distinct sheen. Being 4% it's not enough to really affect the weight of the suit, but it has a very nice look and for most people it looks more luxurious.
Slub can be in almost any material, but in this case it's a type of silk where there's a few imperfections, so to say. It is purposelly made by twisting the fabric as it is woven.. The advantage is that silk often can crease and create a bad looking suit, but slub will basically hide it. You will notice how the fabric will feel a bit rough and have an uneven texture, but it's nothing to worry about!
Now, I started out in this thread, saying that I will be objective towards my own brand - but I noticed how you linked a Boss suit and a Tiger of Sweden suit.
Tiger of Sweden is my biggest competitor right now, where I work. It is the store nearby, and it appeals a lot to the youthful generation of menswear where I live. They are known to be very fashionably in terms of cut (extremely narrow) It looks great on a model guy going out clubbing, but I wouldn't take a business man serious if he wore one of their suits. Buying Tiger of Sweden for retail price, is in my opinion not worth it. The quality isn't great for the price, and their suits are so fashion forward that they will not last as long as a classic look. Let me quickly mention the double boutonnière holes... :D
You should only opt for the Tiger of Sweden suit, if it fits you perfectly!!
Take my words here with a grain of salt, because I really hate Tiger of Sweden's style. The art of dressing is so beautiful and historical, but Tiger of Sweden basically messes around with every single idea of it.. I don't like that.
