Work from small pieces outwards, and leave anything that fixes the size until last. Pattern instructions vary, but nearly all follow this shape, and understanding it lets you sew without reading every line.
One: preparation. Pre-wash, press the fabric, cut, and transfer every marking while the pattern is still pinned on. Apply interfacing now, while the pieces are flat.
Two: stabilise. Staystitch any curve that could stretch — necklines especially — before handling the pieces further.
Three: build the small units. Darts, pockets, plackets, the collar, the cuffs. Each of these is a small self-contained job, and each is far easier while the piece is still flat and light.
Four: join. Shoulders, then the neckline finish, then sleeves in flat where the pattern allows, then the side seams in one run from cuff to hem.
Five: closures. Zip, buttonholes, buttons. These are done once the body is assembled so they land in the right place.
Six: hems last. Length can only be judged on the finished garment, hanging.
Press at every single stage. Press each seam before crossing it with another. A seam that is crossed unpressed can never be pressed properly afterwards, and that is the difference most people can see but not name.
Try it on at the joins. After the side seams and before the closures is the last easy moment to change the fit.
Questions people actually ask
Can I skip ahead when the instructions feel slow?
You can reorder small units freely. What you cannot do is close a seam before finishing something inside it, or hem before the garment hangs.
Why do hems come last?
Because fabric drops, especially on bias-cut and loose weaves. Hemming a garment that has not hung is how one side ends up shorter.
