COLLECTION by John Lewis Ruth
Tweed Jacket, Pink, £99
Kin by John Lewis Quilted
Bomber Jacket, Grey, £59

Squares barely left the SS14 catwalks, and this season the Grid Print is stronger than ever. To master this trend, go for a pared-back approach with these Kin Grid Print trousers. Team with a crisp white shirt and quilted bomber for effortless style.

Kin by John Lewis Sleeveless
Shirt, White, £35
Wishbone Aida Chunky Sweater,
Mid Yellow, £70

I'm very much a fan of “buy now wear now” pieces that I can mix and match. I shall be embracing the skirt shape of the season - the full skirt - by wearing this gorgeous Ted Baker Monny Rose on canvas skirt, with this vibrant chunky knit sweater from our new brand Wishbone. I love mixing texture and bold print. Pared back with tights, this outfit is the perfect transition into spring.

We've seen some great shaped trousers in really fabulous prints coming through for SS14. Teamed with a timeless white shirt, this is one of my favourite outfit combinations. A must-have look on my list comprises these beautiful print trousers from our new brand Wishbone; this great-fitting shirt from Hobbs and a striking coat from Miss Selfridge which really lifts the look, and is great to throw on when dashing between buying appointments.

Wishbone Tia Trousers,
Multi, £80
Curvy Kate Portia Balcony Bra,
Lime / Rose, £28

We're really excited to launch Curvy Kate Lingerie- they offer a great variety of shapes, sizes and colours that we’re stocking from a DD to a J cup. The range is fresh, flirty and fashion-forward, yet designed for perfect fit and support for the larger bust.

Stella McCartney Magnolia Shrugging Collection “We love the on-trend summery neon pink and delicate Japanese leavers lace used in this Stella McCartney range. Floral lace and mesh give a look and feel that is both modern and feminine.”

Stella McCartney Magnolia Shrugging
Bodysuit, Neon Pink, £60

What's not to love about classic animal print from the L’Agent by Agent Provocateur Lucila Collection. Flocked black print on nude is a softer take. As for the dress, based on a vintage piece the brand found at a market, we couldn't resist it! A great body-con piece that gives amazing curves.
