A luggage case or bag of the unstructured type having a semi-rigid support frame with a plurality of strips fixed on the interior of the case, such as at the four corners, forming pockets into which thin flexible sheets or inserts of lightweight material such as plastic material may be optionally disposed or removed. With the inserts removed, the bag may be fully collapsed to a flat position. With the inserts installed, the edgewise rigidity of the inserts supports the body gussets, or walls, of the case in the manner of a fully structured or framed case. In a modified arrangement, the interior pockets are oriented vertically to enable installation of the inserts through the top opening of the pocket. The inserts have some longitudinal rigidity and project in part above the top of the body gusset to provide a structured support to the body and lid gussets and assist in alignment of the lid and body.
