95% of my wardrobe is preloved via Vinted, but occasionally I buy the odd thing that's so great, I know I'll regret not buying.
There is a pair of trousers in Zara just now that are just that: high-waisted, very flattering (I have a bit of a mum tum), very versatile. I absolutely KNOW they will become a wardrobe staple for me, and I've bought in two colours so far.
Link is here: Zara high-waisted trousers they come in 15 colours.
Have added a pic of them so you can see IRL. They come up small - I had to buy an XL.
