Ashley headed out in the capital last night (4 February) to attend the first birthday party of The View From The Shard and got dolled up in a colourful, figure-hugging T-shirt dress, which she wore with a pair of tights and some chunky blue boots.
She also left her blonde hair down and kept her make-up fresh and simple, with peachy nude shades of lip gloss and blusher.
However, her well put together look didn't last all evening, since Ashley soon got caught in a heavy downpour and arrived back home wet through.
Not only was her hair soaking, but her make-up also appeared to have washed off in the rain. Oh dear!
But she seemed to see the funny side and uploaded a 'before and after' photo on her Instagram page this morning (5 February) to prove just how bad the weather had been.
Ashley posted the snap with the caption: "Before and after I GOT CAUGHT IN A STORM."
Joining Ashley at The View From The Shard last night were former Sugababes Mutya Buena, Siobhan Donaghy and Keisha Buchanan, who have now reformed under the name MKS.
And the trio even gave guests an impressive performance during the evening, which Ashley couldn't help but praise on Twitter immediately.
She wrote: "So @MKSOfficial killed it tonight - nice acoustics ladies."
Ashley appeared in Made In Chelsea in the fourth and fifth series and famously dated former co-star Ollie Locke.
