Don't worry about lettIng the vents out, suitsupply will take it back f you return it. I have tried a few of their things. The jackets are amazing, the cuts are splendid. The italia has a bit too much shoulders and is slightly too long for my taste but it covers the ass for this who like that. Copenhagen is great and depending on the cotton used may be too snug even in the same size. I wear a 42 but I'm getting bigger so it's just me. I tried two trousers, the five pocket and the blue cotton one. The five pocket was slim and the 34 was too snug. I'll need to try a 36. I usually wear a 33. The blue trousers were a very strange fit. The 34 were baggy, low seat and narrow at the bottom of the legs. Strange pants, really. The shirts I didnt like. I tried a 16.5 extra slim and while the chest was ok, the sleeves are a little too roomy and the midsection is not slim enough at 21.25 inches. I'm muscular with no belly. So this is my experience so far. I live the suits but my concern is that the pants that come with the 42 are 36. There are limits to what a tailor can do. There should be more separates choice really.
