Nude bra (M&S) and pants (Primark), and I always wear a bra. Black leggings, slouchy t-shirt and hoodie (all Primark). White trainer socks and white trainers. Minimal makeup (mascara and lip balm, mostly).
I've fallen into this uniform as I don't have to think about it. I have 4 pairs of black leggings (2 from Primark, the £2.50 ones, and two from Morrisons, nutmeg brand). Also four slouchy t-shirts (Primark in bright pink, dark pink, aqua and grey) and two long t-shirts (Primark in dark pink and peach). I have two Primark hoodies in light grey and light beige.
Everything is very comfortable and it all goes together, it's quite liberating. I never 'got' the capsule thing before, but I'm so glad I had a bit of a spree back in February, with some vouchers I got for Christmas.
Big plus, they wash great, dry on the line and don't need ironing. I'm going to have a massive clothes decluttering session during this lockdown, and bag up loads of stuff for when the charity shops reopen.
