Look at all the fun details you will sew on this shirt! The Willis top is a stylish sleeveless button-up that will really boost your sewing skills.
This top has a relaxed fit and features a stand collar, front button placket, bias finish at the armholes, and a patch pocket with a button closure. You can pick your own hemline and choose between a straight hem or a curved hem. Look for light to medium-weight woven fabric like poplin, shirting, batiste, lawn, voile, seersucker, Swiss dot, linen, rayon challis, and silk crepe.
