I'm learning to tailor my shirts. From all i googled, i picked side seams method as it is easy and looks good.
Usually side seam on my shirt looks like this:
But i also have wrangler shirt and i guess it tailored, cause its seam flat, but still looks nice:
When i sewing side seam it looks wavy:
How can i make it straight and flat like the wrangler's shirt?
Another question - how to deal with armpit, should i just stitch over it with same fabric width?
That`s what i did, but what if i need to tailor only sleeves or body, how to start/end seam at armpit?
And one more question how should i and seam at cuffs - sleeve becomes slimmer, but the cuff still wide:
