A v-neck cashmere sweater, because it's comfortable and chic . If you can, go for Eric Bompard, they are definitely the softest that I ever tried. But there are other options, Zara, Gap, Uniqlo offer good value for money. Cashmere sweaters will stay in your wardrobe for ages, I was looking at my cashmere sweaters the other day and I found one from early 2000 which my mother bought for me in Galeries Lafayette (yes, I was young back then)!!! This was when cashmere sweaters started to become affordable and everyone went crazy for cashmere and pashminas (do you remember that??).
A pair of comfortable wedge booties in which you should be able to walk for hours. These are from Topshop but if you are willing to invest in a great (but expensive) pair check net-a-porter.com.
A delicate gold necklace for every day, like this initials coin necklace from Laura Lee. Mine has my two sons' initials, one on each side, I just love it!
A long flap wallet like the Chloe Marcie. I usually go out for a quick errand with just a wallet, for me it's like a handbag, so it's important to have a gorgeous and practical one. You can buy this one at luisaviaroma.com, or a cheaper alternative from Mango.
