On buying multiples

I usually don't buy multiples of one item. Did it once a few years back when I purchased two identical pair of jeans that fit really well and had one hemmed for heels and the other for flats. Orange and purple houndstooth print tshirt Go by Target Then came the houndstooth tshirts one is black and white and the other above. White shorts Larry Levine - Orange bag Lanvin Red flats Stradivarius Upon purchase I thought I'd wear them a lot. The fact is they were never worn. Oh, the same happened to the jeans, they got little wear. What's your take on multiples ?
