Corrin uses binders from gc2b, which is billed as the "very first gender-affirming apparel company that is trans-owned and operated". Her post prompted a series of supportive messages from some of her showbiz pals, including singer Paloma Faith.
She wrote on the photo-sharing platform: "Beautiful pictures xx"
Artist Arlo Parks described the photos as "angelic" and the official Netflix account responded with a series of heart emojis. Meanwhile, Corrin previously suggested that her new-found fame has been made more manageable because of ongoing coronavirus restrictions.
Speaking about her rise to stardom since appearing in The Crown, she explained: "When the show was coming out, we weren't able to be together as a cast to celebrate it.
"We were so proud of it, but haven't seen each other since [before] the first lockdown. It has been so strange - and sad. But perhaps it's a blessing in disguise. A friend said to me that at least it has meant that the focus has been on the work, not on events in, say, LA – and that's what it's all about for me.
"It has also made the whole explosion more manageable. I've had time to
come to terms with it, I suppose."
