Attending the Nordoff Robbins Silver Clef Awards 2014 at the Hilton on Park Lane in London, the classical singer looked ready for the occasion in a glam frock and heels.
With the sun shining, Katherine chose to wear a retro shaped frock, which featured a green tropical flower print and came just below her knees.
The 34-year-old, who recently got engaged to Andrew Levitas, teamed the dress with pointed nude heels and a sunkissed glow.
After nailing another chic look earlier in the week at Wimbledon, it seems like there's no stopping this Welsh beauty!
And Katherine looked amazing in the hair department too, wearing her golden-hued locks in soft loose waves, a deep side parting and pulled round to the side.
Katherine also sported a flawless complexion, groomed blows and super fluttery lashes. But what we love the most is her bright red pout!
Fancy stealing Katherine's lush lips? Well to get that perfect matte colour, we recommend using MAC's Ruby Woo (£15.50).
This shade is a cult classic and will instantly add a glam finish to your look – though the formula can sometimes be a bit drying, so make sure to prep your lips with a nourishing balm first! We love Burt's Bees Beeswax Lip Balm Tube (£3.69) - a natural formula loaded with soothing ingredients.
While can't have Katherine's dreamy hair and fab wardrobe – we'll definitely be nabbing her lippy!
