"Orla is a semi-fitted shift top with delicate details offset by a modern exposed zip. Classic at first glance, a closer peek reveals a wealth of interesting design details to develop your sewing repertoire.
The bodice is shaped by curved French darts at the front, with contour and shoulder darts at the back for a great fit. The booty-shielding dipped hem is finished with a facing.
Choose from full length or cropped sleeves with a subtle pleat at the shoulder. Keep it understated with the plain neckline version, or add the adorable snowdrop collar.
Orla looks great over skinny jeans or leggings for every day, or with slim-fit trousers or tucked into a skirt for the office. The collar version makes a lovely layering top to wear under knitwear."
