Shirt and tie with cardigan for job interview?

Just wondering if this would be acceptable for a job interview in the teck industry. The interviewers will probably have a suit on but I do not want to buy one as I need to put up weight for my sport and it would be too small in six months if I reach my goals. I could buy a bigger suit but there is a chance it would never fit me right if I do so I am not going to buy one or rent one for that matter. It is for a internship in Amsterdam.
I have shirts and ties and will wear formal chinos with shoes.
Here are some examples:

Let me know what you think. At the offices the dress code is casual enough with about half wearing t-shirt and jeans.
