Really? 3? Heather, you are a spartan goddess. I figure I'd need a minimum of 5 (flip flops, street sneakers, gym shoes, nicer pair, and boots).
Then again, I'm probably a bad judge of these things. I lean more toward the Dobby side, but y'all probably could've guessed that.
Do I need 28 pairs of Chuck Taylor All-Stars? Probably not. But I like them.
The only time a person can have too many shoes is when they can't physically fit any more in their house. I'm not going to count how many I have because I don't want to feel obliged to admit it. But it's many. Some of them even fit me properly.
I was slightly traumatised when opening the wardrobe the other day caused a minor shoevalanche.
At least I only have three handbags. That I use regularly, that is.
Maybe some people have unattractive toes and don't like the way they look naked and need to keep them painted even in the winter when they're inside socks and boots most of the time anyway.
I mean, not me... of course... so I wouldn't know, but I have this friend. 
Er, yeah. That line of thinking is, er, completely unfamiliar to me. Honest. A bit.
