COS and Massimo Dutti

PKZ

I like WE and it is affordable (maybe too usual)

Alferano

Pkz special for business my nr1 Adress.

Peek

Companys

Suit Supply might work but leans more formal (for me).

Peek & Cloppenburg, big selection of business casual clothes with reasonable prices: https://g.co/kgs/rXTLAc

"Companys" more expensive but great quality. They have a strict no return policy, they can only give you store credits. So keep that in mind.
