Let's take a peek at her stylish (and slightly too summery) foray into British winter below.
Selena was first seen leaving her hotel in a navy blue off-the-shoulder Cushnie et Ochs minidress, Lita Small Cat Eye Frames from her stylist Kate Young's line for Tura (USD $345), and a pair of Velvet Adrien Tie Slides by Trademark (USD $648).
If you're getting cold just looking at her, you're not alone! But, we guess the #fashun is worth the risk of a few goosebumps.
Her next look at BBC Radio One was more weather-appropriate, as she wore a black studded dress by Proenza Schouler with a white long-sleeve shirt underneath. She paired the ensemble with classic black pointed-toe pumps and the same Tura sunglasses.
The singer next appeared at KISS FM in a long-sleeved Isabel Marant floral dress with red suede Mansur Gavriel slingback heels (USD $297).
Following on from her feminine display, Selena opted for a more masculine take on London style by wearing a plaid coat by Fay. She paired the gorgeous piece with a black Prada miniskirt, black turtleneck sweater and the same Mansur Gavriel heels from earlier in the day.
For an afternoon event celebrating the Coach x Selena Gomez collection, the singer wore the embellished penguin print shirt dress by the brand with custom black lace up western boots and round sunglasses.
Finally, the star enjoyed an evening at Royal Albert Hall for the British Fashion Council's 2017 Fashion Awards. She opted for a romantic gold-tinted silky Coach dress, which she paired with white boots and a cosy fluffy jacket on the red carpet.
We can't wait to see what the stylish star wears next!
