My first try at a pattern from Lekala. It’s a Russian online company, for only 2€ I ordered pattern 4079, and if you give them your measurements they send you a PDF to your exact size! And it fits per-fect-ly. Now I’ve made a prototype using an unironable sticky polyester fabric, hence bulging seams. I’ll look for a lovely cotton or viscose jersey and make a new one!
and what it looks like at Lekala.
