What Is Flat Seam Design?
Flat seam design is where the seams of a garment are stitched completely flat against the fabric, eliminating any raised or bulky ridges.
How it helps:
Instead of traditional seams that create visible lines and bumps underneath clothing, flat seams lie smooth against your skin. This creates one continuous, seamless-looking silhouette from your back, hiding all your back fat, so everything looks perfectly smooth no matter what you wear on top.
