And we couldn't help but bring your attention to her natural beauty at the Erdem Spring/Summer show on Monday (19 September).
It's no wonder Kit Harrington is so besotted (yes, the GoT stars are a real-life item in case you didn't know).
Rose rose to fame as Gwen Dawson in the first series of Downton Abbey back in 2010.
She then met her current beau Kit when she played his character Jon Snow's ill-fated love interest in HBO's Game Of Thrones.
Oh, how we miss that storyline...
But back to reality. The gorgeous redhead hit day two of LFW on Saturday (16 September) when she took to the Emilia Wickstead catwalk show.
And on Monday she hit the biggest day of LFW by taking in both the Erdem and Christopher Kane front rows alongside everyone from Daisy Lowe and Jenna Coleman to Alexa Chung and Salma Hayek.
LFW is often the time for crazy make-up and wild outfits (and we don't just mean on the runways!), but Rose played it down and totally nailed it at Erdem.
Her hair was left loose and ever so slightly wavy, while her skin and features did all the talking through very minimal make-up, thanks to cruelty-free make-up artist and Humane Society International ambassador, Justine Jenkins.
Strong eyebrows, a little definition around her eyes, rosy cheeks and subtly pink lips were all it took to give Rose an absolutely stunning glow. And a little birdie told us that those lips were created with none other than Burt's Bees Tinted Lip Balm in Pink Blossom, £5.99, burtsbees.co.uk.
We also like Benefit Benetint Lollibalm Lip Balm, £14.50, boots.com for a similarly pink wash of colour.
Now, where's that Jon Snow when we need him?...
