Too much?!

I have thought about this topic for the last 4 days and i have come to the conclusion that you can never have too much or rather i dont think i have too much of anything.
as long as each item has a purpose and use then it not too much/many!
example:- 5 of these is too many black shoes
these 5 is not too many black shoes get it ?

so what can i not stop buying :- whatever i like for a season and i cant buy just one. --long necklaces, dresses this season.
