Read fabric descriptions and labels
Separate the visible weave from the stated fiber blend.
Distinguish structure and fiber
Mesh and lace describe construction. Polyester, elastane and modal name fibers. A description may give one without the other.
Check contact points
Look at seams, elastic and decorative pieces in close-ups. Review the care label for washable and delicate parts. If materials are uncertain, ask for a photo of the garment label.
Check a different garment by its own measurements
A matching teddy or bodysuit also has a torso length to consider. See the teddy torso fit guide before comparing one-piece styles.
