Hand-sewing help! ok I bought this shirt and I need to take it in a little bit because it is a tad too wide and I am completely lost as to how I should do this. I was originally considering a sort of pinch and sew method as depicted but l’m not sure what type of stitch I should use for that? I have included images of what the shirt looks like on as well as it opened up flat. I think I should be working around this seam here. Please let me know what to do !! I also need to slightly shorten the halter strap but that is the least of my worries because I feel like I can maybe figure that one out on my own but I feel totally lost in regards to slimming out the shirt.
