If you are working with a standard pattern for leisure wear summer shorts, a simple straight stitch seam will be good enough. If you are making sports shorts, that will require a stronger finish, I suggest a flat fell seam.
To emphasize seam lines, you can flatten the seam flaps inside the garment and then sew them down on both sides of the seam on the outside of the fabric in contrasting colored thread. Another idea is to add a contrasting trim to the seams of the garment, like rick-rack, braid, or sequins.
After the seam is sewn, a seam finish can be applied to the outside edges of the seam allowances to keep them looking neat and prevent fraying. Examples of seam finishes are a zig-zag stitch, using pinking shears for a pinked finish, french seams, flat-felled seams, etc.
