Does Drycleaning Shorten the Life of Garments?

Nope, quite the contrary, - frequent cleaning prolongs the life of a garment.
Not only do stains set with age, making the garment unwearable, but ground-in dirt and soil can act as an abrasive, causing rapid wear of fibers. Also, insects are attracted to soiled clothes (particularly to food or drink stains) and will eat holes in the fabric.

That said, you should be aware of one part of the clothes care process which can cause an appearance change, particularly with fabrics such as wool gabardines.
Over-pressing, which usually results from not changing foam pads on presses frequently enough, can cause a flattened appearance, to the point of having a glazed, shiny appearance on gabardines.

Areas where garments are stored should be dark and clean. Light fades colors and attracts insects.
