Denim Fetish

Denim can never be boring because it goes virtually with any outfit. You can make denim appropriate for after-work drinks, a first date or maybe even meeting parents for the first time. Sometimes the occasion calls for something not quite formal, but something that is still pretty and polished.
For a formal look, a pair of dark jeans can look just as professional when paired with a jacket and colourful tank. 
A dark rinse denim can even also be an alternative for black pants in some situations, depending on where you plan to wear them to but check with your office dress code first before wearing it.
