BUT, I have to say the instructions for this very simple top are terrible!! There are only 3 pattern pieces and I know I have even made a similar top from Burda before. (Fehr Trade posted the same thing on her instagram so it's not just me having a dumb moment).

Despite the awful instructions I do actually love the finished top.
Anyway I would say ignore the nonsense about cutting into one side of the front self facing (the very first step!) as it is not needed. I guess the idea is that the other front passes through the slit, but it's not clear later on. Even in my bulkier fabric I don't think it makes any difference. The instructions also have "(NAHT)" in two places and goodness only knows what that means!! Neaten allowances together pops up at the end of a few other steps so maybe something like that?!?
Stupid instructions aside this is a really nice pattern. I made mine in a heavier fabric than recommended - a double knit - so mine is more sweatshirt than blouse. I like using fabrics like this for wrap tops though as the "stickiness" of the fabric makes it more secure. I originally planned to make this in more of a t-shirt knit and I might still go back and try it.
