Do you know how to build a capsule wardrobe? If I was doing it from scratch, I’d start with this:
Three pairs of trousers - for example, one pair of dark indigo jeans, one pair of plaid or plain trousers, one pair of corduroys or chinos.
Three shirts that each go with each of the trousers. Two patterned, one plain, or whatever. But they must all coordinate with each other.
Two jumpers that go with each of the trousers and each of the shirts.
Two skirts. Again, they need to go with everything above.
Two other tops, for example one black or navy turtleneck, one other colour v neck - again, chosen in colours that match all of the above.
Two or three dresses, again keeping everything coordinated.
One or two blazers. One in tweed, i’d suggest, and one black or navy one that can be dressed up or down for casual/smart wear.
A couple of pairs of flat shoes, a couple of pairs of heeled shoes. One pair of smart shoes. Again pick within a narrow range of colours so they all go with everything.
A few pairs of simple stud earrings. A very small and subtle necklace and pendant. A watch that echoes colour of the overall wardrobe.
That’s all you need. You will be able to get loads of different outfits from that.
