Reena: ‘I raided my mum’s closet a lot when I was younger – sometimes I would tell her… sometimes not. I remember one pair of Miu Miu ponyskin shoes that I used to go out in a lot, and these amazing, white, horse-embroidered Stella McCartney jeans that I stole a lot as well. How she didn’t know… Actually, thinking of it, she probably did know, but she kept quiet.

‘We’re really lucky because we’re very similar sizes. Our shoe size is about the same and our build is similar. Mum’s bustier than me, but I’ve got a bigger bum; I wear a lot more jewellery and heels, whereas she’s

not as into that stuff. But even with these differences there’s a natural crossover. More than once, we’ve gone into the same shop at completely different times and bought exactly the same thing. Sometimes we can be sensible and collaborate on investment purchases – there was a beautiful YSL handbag we both wanted that she ended up buying for us to share.

‘Now that I’m in my 30s and we live apart, sharing our wardrobes takes more planning – usually it happens for special occasions or when we’re on holiday. Actually, the dress that I wore for my 30th birthday dinner was a dress my mum bought from the Anna Sui shop in New York when I was 14! It’s the most beautiful blush-pink, 1920s negligee-style dress – just stunning, and somehow she’d never worn it. I asked if I could borrow it and she didn’t hesitate at all. She has the biggest heart of anyone I know.

‘I’ve always known my mum was stylish. I remember being about five years old and watching her getting ready to go out for her 30th birthday, wearing this gorgeous black dress with feathers around the neckline. I remember being so jealous that I couldn’t go out with her, because she was so glamorous. I always thought I was very lucky.’

Ruby: ‘Reena probably started borrowing my clothes when she was 14 or 15. She’s always had a sense of style and known what she likes, and we were roughly the same size from then. There was a stage when she’d borrow my shoes and I’d think, “I haven’t worn these – who’s worn them?” or when I’d find a dress with a make-up splotch on that she’d just slid back into the wardrobe thinking I wouldn’t notice. Of course I noticed. But generally I loved seeing how she would wear my pieces.

‘In terms of our styles, more is more for her – she wears a lot of jewellery – whereas I’m a bit more pared down. Sometimes Reena pushes me to try different things than I might have otherwise, like when

I look at her and think, “Gosh, I never thought of wearing something like that. Could I pull it off?” And she’ll tell me yes or no. She’s a really good barometer because I trust her taste and I know she’ll always be honest with me.

‘Obviously she’s not my carbon copy, but it’s nice to see that she’s picked something up from me. She used to sit there looking at my shoes, gaping, and now I look at her Louboutins in awe. I’m like, “Jesus, woman, how can you walk in those?” – and she walks like a swan, she’s so elegant. I do look at her and my jaw drops.’
