If I'm near a TK Maxx I'll often pop in to see what they have. You can pick up a Daniel Hector or Pierre Cardin for €10 sometimes. Not amazing quality but perfectly fine for everyday wear. The odd time, you'll find a nice Baumler for around €12 which look like they'd retail for about €50 elsewhere.
I don't want to belabour the point would I would urge those interested in menswear to disregard 'brands' and focus on sourcing natural materials, construction and country of origin.
