Never one to miss a theme, Kate Middleton looked loved up on today's trip to Mumbles in South Whales, wearing a Valentine's Day-inspired outfit while strolling through the seaside town with her husband, Prince William. 

The Duke and Duchess of Cambridge were carrying out a day of engagements, starting with a trip to Royal National Lifeboat Institution Mumbles Lifeboat Station near Swansea.

After a glamorous date night spent at the Baftas on Sunday night, the couple looked at ease together and even appeared to coordinate their outfits in honour of the Welsh flag, with William donning green and Kate wearing red.

Kate looked rosy in her Valentine's Day-inspired outfit, amping up her look with love heart-red accessories. The Duchess once again pulled out a favourite red midi dress from high street spot Zara, featuring a high neckline, voluminous sleeves and paired with a black belt around the waist.

She matched this with yet another military style coat, this time choosing the Bianca Maxi Coat from Hobbs in a rich navy blue. The double breasted silhouette, embellished with burnished crested buttons and shoulder epaulettes, emphasised Kate's tall frame while adding a touch of luxury to her outfit. Even better, the coat is now reduced from €420 to €310. 

Ensuring she stayed warm by the seaside, Kate added a pair of knee-high black suede Zara slouchy boots with a small heel. 

To keep the pops of colour front and centre, Kate added a stunning pink and red heart-print scarf to her look, layered under her coat. The Kamala Pink Blush and Red Heart scarf from Beulah costs €138 and is made by Nepalese women through the company's sustainable organisation. 

Completing the look was a neat scarlet red Mulberry clutch bag in a crocodile pattern. 

As usual, the Duchess wore her hair in soft curls, this time pulling her bouncy layers back into a chic half-up-half-down hair style. Her makeup was pink and rosy, keeping the radiant glow she got from the sea in her cheeks throughout the day.
