Two things. I bought a leather bucket bag in Florence, 20 years ago. I knew I had to have it though couldn't really afford it. I have used it consistently, ever since. I have a Mulberry (DH bought for me, as a surprise) and it vies for attention with my Florentine favourite. A LOT of money at the time but well worth it.
Second (not clothes, again) an item of makeup I bought in New York. I have tried to replace it many, many times but cannot. It is my all time favourite and the empty container sits in my drawer, as I even love the smell of it.
I'm not one for clothes so much. More an accessories kinda girl!
