I'm looking for a versatile black flat to be worn with skirts and trousers. Due to the temperamental British winter the shoes must work with different types of hosiery, below are four option I'm considering and I would appreciate if you could vote on which you prefer:

Option 1, Clarks

Option 2, Next

Option 3, Office (suede) if this shoe was any fabric other than suede I think I would have a winner

Option 4, Office

Edit: Added fifth slightly over budget
Option 5, Asos

Do you think I'm being unnecessarily fussy in only choosing leather shoes?

Do you think none of the above are appropriate and I should continue my search?

Many, many thanks
