46, size 16, basically the archetypal middle class, middle aged, working mum.
I wouldn't call it a 'capsule' wardrobe, but I think I'm at a stage where I don't need anything different, so any future purchases are just replacements for what I have.
Here's what it comprises:
Four pairs of near identical Sweaty Betty ankle cuffed yoga pants (all black). Not too sporty, can be worn day to day.
8 or so thin under layers in black or cream (largely uniqlo heat tech).
4 round neck cashmere jumpers (from M&S or Cashmere and Cotton). In black, electric blue, brown, and beige.
One pair of wide leg dark navy jeans.
One pair of ankle cuffed mum style jeans.
One pair black cigarette trousers.
One boxy cardigan (oatmeal).
Three mock turtleneck jumpers (one black, one navy, one grey).
One ski style puffer.
One Sweaty Betty waterproof trench coat.
One tailored wool coat.
Two cashmere snoods.
I do have other clothes, but so far this winter I've basically worn this on rotation.
