So many variables with fashion and so little info from the OP.
If you are an entrepeneur , a suit would nicely complement who you are.
If you are a punk rocker, then a suit is a no no.
The OP needs to pick a stereotype and dress the best for that stereotype.
The big universal tips with fashion/style is , get them fitting perfect, (get them tailored if you have to)don't over do the colours, pick ones that complement each other, keep things simple.
This is a simple quick and versatile look that can work in formal and casual setting. Was gonna rolll sleeves up and reveal my matching brown strap watch.
Yes it is a pic of me, and i do get complimented on my style often and get success as a result, especially on the sock-less look that us Brits like.
