Clothes are important in presenting a good first impression and have become a necessity for life. They can also be a great form of embarrassment. A popped button might expose a pale stomach. A skirt not done up properly may expose undergarments, or worse, fall down. So much for a good impression. As well, tripping over shoelaces makes one look like they have the grace of an elephant.

Perhaps this is where Whitcomb Jackson came up with his great invention. A fastener was created in 1891, later named the zipper. This creation revolutionized the fastener and clothing industry. The zipper contains two separate rows of teeth that can be interlocked to close a garment. The slide of the zipper, used to open and close the device, consists of three wedges. One, at the top, is used to detach the teeth and force them apart.

The bottom two force the teeth together so they inter mesh closing the fastener. Without the use of this slide it is practically impossible to open or close the zipper. This quality makes it a fabulous fastener. The zipper was not a very popular device u nail the beginning of the Great War. It was originally used for doing up boots, since the buttonhole boots were too much of hassle.

The US Navy realized in 1918 what an asset it would be as part of their flying suits. The suits became easier to put on, decreasing the preparation time of the soldier. From then they began to appear in the garment industry. They first appeared in men's pants in 1920, to zip up the front. They did not appear in women's clothing until the late 1920's. Now they appear in most articles of clothing because they are so convenient.

Zippers have become a great convenience as far as getting dressed is concerned. The cut time off dressing and neither breaks like buttons nor poke like pins. They only become a nuisance when someone walks up to you to quietly whisper in your ear that you are "flying low.".
