Stretch fabrics — jersey, cotton-spandex blends, ponte, knit fabrics, and similar materials — behave differently from woven fabrics in almost every way that matters for alteration. They stretch, they can ladder or run when cut, they require different stitch types that maintain the fabric's stretch, and the seam finishes needed to keep them looking neat are more technically demanding. Stretch fabric alterations in Grenada are entirely possible, but they require a seamstress who is comfortable with knit construction techniques — not all are.

A regular straight stitch will pop when the garment is stretched — the thread breaks because it can't extend with the fabric. Stretch garments require either a zigzag stitch, a stretch stitch, or ideally a serger/overlocker to sew seams that stretch with the fabric.
The second challenge is that stretch fabrics are often cut on the grain in specific ways to maximise or control stretch direction, and cutting into a stretch garment incorrectly can compromise how it drapes and fits on the body.
Taking in the side seams of a jersey dress or knit top is a standard stretch alteration. The side seam is unpicked, the excess fabric is taken in, and the seam is re-sewn with an appropriate stretch stitch. The result can transform a garment that's too wide through the body into a properly fitted piece. This is one of the most common and useful stretch alterations.
Hemming knit and jersey fabrics requires a stretchy hem stitch rather than a standard blind hem. Options include a twin-needle hem (which creates two rows of parallel stitching with a zigzag on the underside), a cover stitch (if the seamstress has a cover stitch machine), or a zigzag stitch. A well-executed stretch hem is almost invisible; a poorly executed one puckers and breaks.
Shortening the length of a jersey or ponte dress is achievable. The original hem is removed, the dress is shortened to the desired length, and a new stretch hem is applied. If the original hem had a distinctive finish (rolled hem, lettuce edge), replicating this requires additional skill.
Ponte fabric (a denser knit used in structured dresses and trousers) is more stable than jersey and can be altered in ways that are closer to woven fabric alterations. Waist taking-in and seam adjustments on ponte garments are more straightforward than on fine jersey.
Adding fabric to a stretch garment to make it larger is significantly harder than taking it in — the original fabric must be sourced exactly, which is often impossible for a specific knit or jersey. Restructuring the neckline, armholes, or overall silhouette of a stretch garment requires advanced tailoring skills. And fine, lightweight jerseys are harder to alter invisibly than more stable knits.
