Smart comfy shoes (I like leather trainers and birks), a huge minimalist hat and chic sunglasses.
For me it's a limited capsule of good quality (linen, cotton) clothes in limited colours, eg. only black and teal, or only navy and cream. Limited simple jewellery and make up. Hair braided loosely or in a nice up do. Nails natural, clean and shortish.
No huge ugly Trespass or Go Outdoors backpacks if going anywhere decent 😅😅 nice looking minimalist one will do, or a sling bag for daytime.
Sun cream, water, hat, glasses.
In truth, I'm usually juggling three pairs of specs, paying slowly with two purses and taking ages to sift through every unusual coin, I'm hot and shiny and I have some weird stain on my trousers/armpits, and I'm peering at Google translate with a furrowed brow and terrible posture because I'm tired 😅
