It has a button opening at centre front and a drawstring waist with inseam pockets. View A hits 20” from the waist. View B is maxi length and hits 42” from the waist and includes a centre front slit.

    I’ve only discovered the Southport this year and it has now become one of my favourite summer dress patterns. It’s very simple and quick to sew and incredibly comfortable to wear. If you’re not a fan of bias binding, this is not the pattern for you. The neckline and arms are finished that way. There are buttons at the front but they don’t have to be functional as the neckline is wide enough for the dress to be pulled on and off.
    There are 2 skirt lengths on offer as well and although I’m not usually one for a maxi length I’m very very pleased with this one. I’ve worn it quite a few times already and I know that will continue. This is my second version. I’ve also made the knee length one.
    The instructions are great and the finishing on this is superb. Apart from side seams, everything is enclosed – and I did french seams for mine anyway.

    This is my second (finished) Southport. (There was a third but I made a size down which wasn’t going to fit so gave up.) I made it in a gorgeous Seasalt cotton voile.
    I made the size 14, I have a short body and found the neck line a little low on my first version, so removed 2 inches from the front bodice straps. I also scooped out the arm scythes by a 3/4 inch and lengthened the skirt by 2 inches.

    I am very pleased with the alterations as its a perfect fit now! It has been so lovely to wear in this hot weather!
