this was fairly easy pattern to sew. i sewed a 36cm because of my large chest but as you can tell it's wide it my stomach region. i not really a big fan of woven pjs but i need some and had the fabric. for the upper bust elastic i just serged on 1/4" elastic the, fliped it over and zigzaged. i also used 1/4" elastic to gather the upper bodice then sewed trim overtop the gathers.
