On the Enterprise, no one has to worry about getting their clothes dirty when cooking because the replicator does everything for them. Here in the real world we have to cook our own grub. If you are a messy cook like me, you need an apron. I always end up with flour, sauce, and other stuff stuck to me.
The worst is bacon grease because those stains never come out. This is where these Star Trek: The Next Generation aprons come in. There are three colors to choose from with red, gold, and blue options.
You can get your own Star Trek TNG apron at ThinkGeek for $24.99(USD). This should tide you over until replicators are invented.
