Gifts, bows and dresses
Bows and ribbons have found their way on to gifts and girl's dresses. An implicit invitation to undo the bow with a promise of a pleasant discovery to be reveled at the end of the unwrapping process. This makes that the purpose of the dress and wrapper the same. That is too keep the object of interest conceled and be discarded when the invitee accepts the invitation.
This observation does not however explain the need for the fastner and conceler to be to ornate. Why the ribbon and bow instead of rope and knot? With the ornate constraint leads to a different result. The ornate fastner and wrapper suggest the intention to elevate the value of the object is encloses.
If so, then why are all dresses not ornate? Presence of bow and wrapper, enclosing an object, implies the presence of at least three entities. Inviter, invitee, and the non-invitee. As in, there is no value in a bow if it was not to be undone, hence the invitee. Since there is an invitee, there has to be a non-invitee. If all dresses are ornate, then no dress is ornate and elevates the preceived value of the object in a non-ornate wrapping.
The discussion suggests the dual role of ribbons and bows on gifts and dresses. Where they are an invitation on a gift and preceived value enhancers on a dress.
