Rebecca W.

“The cheerful floral print is what won me over. I’d pair these with a plain white tee and trainers for a relaxed weekend look. And those pockets are a lovely touch!”

Rebecca W.

Nicola H.

“I usually stick to navy, so this pink is quite a change for me! The mix of patterns gives it so much character without needing much jewellery.”

Nicola H.

Christine M.

“My favourite combination from The Tennant Sisters. The deep green looks lovely against the white leaf-print jacket, and I like having pieces I can style separately.”

Christine M.

Alison B.

“The little birds tucked into the floral pattern caught my eye. Blue and white is such an easy combination to wear, especially with neutral trousers and sandals.”

Alison B.

Sandra P.

“A bit different from my usual florals! I love the blocks of colour and the simple neckline. This is the sort of dress I’d choose for a sunny lunch outdoors.”

Sandra P.

Deborah S.

“The long shirt style is right up my street. Rolled sleeves, flat sandals and a watch would be all I’d add—an uncomplicated outfit that still looks put together.”

Deborah S.
