Pumps problem, so am forced to ask if it is possible to have too many pairs of wedges?

[Pennies]

Can't find the navy pumps I'm after but I have fallen for yet another pair of wedges (I currently have 3 pairs) from Boden.

Is 4 pairs too much?

If so, can anyone help me find some navy pumps that don't look like they should be worn by anyone a day less than 60 or on a boat.

these are nice but not navy here
