No. 1: Lauren Blouse

Ascension, £55.00

We're loving Ascension's new line of clothing, and they've come up trumps with their Lauren Blouse. With a playful twist on the classic white shirt, this beautifully crafted shirt boasts frill cuffs - we love - and cute pin tucks, this shirt looks great tucked in (as pictured) or left out, with its cute drawstring dropped waist feature. Loose fitted, you can just pull over as it's not button down, instead it features a half button front yoke.
