@The Noodles, welcome back. Trousers look decent. I would try to buy things that are a bit more seasonal in nature (e.g. Fresco in summer, flannel in winter) as it will serve you well in the long-run and it's pretty easy to build up a seasonal odd trouser wardrobe when you have to wear a suit 5 days a week and thus don't spend much time in odd trousers. The jacket in question looks like a navy suit jacket to me and not a proper blazer.
