Hi everyone!
I recently lost a lot of weight and decided to buy some functional clothes for my new corporate job. I will work in the IT department of the bank with zero face-to-client time. Dress code is business casual. All the people who interviewed me were very laid back in their outfits, especially since it is summer.
I bought some clothes and need to decide if I should return some of them. Also, I will take the suit to the tailor.
To conclude, my main question is whether it looks good on me? And if you have recommendations on what else would be nice to buy to make an office capsule wardrobe?

Hi everyone! I went shopping once again and bought different outfits. Help me choose what to keep and what to give back.
About me:

I don’t like patterns or different colours; I want to think about my clothes for this day for no more than 2 minutes, and I want everything to mix and match. I like to look collected and don’t mind look little bit too formal for a dress code.
I am on the track to lose 3-5 kilos in next three months, so I aimed to tighter options to ensure it will not look too loose in autumn.
About the job:

It’s the IT department of the bank, everyone was very laid back on dress code in the interview, I don’t have any time with clients. Dress code is business casual

I'm starting a new job in the autumn, and I decided to buy a suit during the summer sale. I am losing weight, so I don't mind if it's a little tight, but I am concerned if the shoulders look odd. So, do they?
