Do the lapels of your blazer or suit coat look like a tiny rollercoaster at the edge?  Ripples are fine in the ocean but not front and center of your favorite jacket!  As garments get older the components used to hold them together age as well. 

When two pieces of fabric are sewn together there is often some sort of interfacing or bonding material to give the edges of the item extra stiffness.  Many of these bonding materials break down with heat and acceptable cleaning methods. 

This softening or break down creates an uneven appearance and a rippled effect along the edges of the lapel.  We can apply a spray sizing when we iron the garment but sadly this is just a temporary fix…it will continue to get worse since the interior structure of the fabric has been compromised.
