Approaching 40 and in the last 5 years I've:
Ditched Primark undies for better fitting bras and seamless pants. And some Spanx. Clothes definitely hang better.
Stopped with the heavy black eyeliner flick on top lid and full face makeup. I think I look better with just some mascara, blusher and tinted lipgloss.
Switched to classic cuts with a limited colour pallet and good quality fabrics. Thanks to eBay i have some lovely timeless designer pieces.
Become obsessed with making sure my whites stay brilliant white and dark clothes are not faded. And ironed perfectly.
Ditched big, clunky statement jewellery for simple fine jewellery. I don't wear it on a daily basis but have treated myself to a vintage Rolex which I wear everyday.
Stopped lightening my naturally black/dark brown hair, no more highlights etc. Hair looks and feels healthier and I don't have that cheap faded, dry ends look anymore. It's usually tied up in a ponytail (instant facelift
)
Banned peep toe shoes. There is nothing good about peep toe. Pointy classic stilettos in black or nude otherwise flats/loafer style. And no concealed heels/platform.
Been wearing smart belts with my jeans/trousers.
Bought a few large silk square scarves to drape over shoulders (and add a bit of colour) but haven't used them yet.
Become too lazy to wear dresses/skirts - too much of a faff with having to shave m/wax. My uniform for going out in the evenings now is blazers and jeans. Boring but easy.
Stopped seeing clothes as seasonal. I no longer differentiate between summer wardrobe and winter wardrobe. Most things I wear can be layered to suit the weather.
Learned that floaty tops are a no-no for my broad shoulders.
