The video is a short film we made using this costume (as well as another costume).
Before you make this costume, realize that it is striking, kinda scary and very form-fitting. For these reasons this is great for clubbing, public events, parties with adults, or maybe for a haunted house. Although it won't show any skin, almost every nook and cranny of your body will be visible. Personally I would feel uncomfortable wearing this to a church or school Halloween party. And if you're self-conscious about your body, this costume is not for you.
This instructable was made after-the-fact, which means I don't have many step-by-step photos. Fortunately, superpants made a version of this same costume and has a lot of helpful photos which you can use to help you make the mask.

Step 1: The Body Stocking
The body stocking is what really makes this suit stand out. Rather than looking like you're wearing a costume, it will appear that you are just walking around in your own green skin! But it is important to find the right one.
For some reason Asia is really into these things. There are dozens of websites where you can buy them. In Japan they are called "Zentai" suits. A quick search online should yield many options. Add "wholesale" to find several sites that offer wholesale prices, even if you only buy one! I recommend using the safe-search feature on your browser to avoid a lot of, um, unusual websites that tend to come up when searching the term "zentai".
Some American and British sites offer this same product, but as something to wear to football games rather than as a generic costume base. Be careful with these as some will print their ugly logos on them.
A zentai is the way to go since it covers the entire body including the hands, feet, head, and face! It is usually made of lycra. If you don't want to buy one you could probably use some under-armor, a dance leotard, or some onesie pajamas. This will greatly reduce the alien effect though.
2. Order your suit.
I spent a lot of time searching and bought mine on sale. It cost about $35 once I had paid for shipping and everything. Most sites will charge closer to $50 and up, but look around for a bargain.
Order it well in advance since it usually takes two weeks or longer to arrive from China or wherever.
Some sites also offer a custom sizing option. You send in 8 or so different measurements and they make it to your size. This is the way I did it and I was very pleased with the result. Some sites charge extra for this service and others don't.
Choose your color. Mine was green. Other colors that would be cool are gray, blue, or even metallic green or silver. Keep in mind that you will need to match this color exactly when you paint your mask.
It can be hard to tell exactly how it will look from the pictures, so be prepared for a slightly different color than you see in the photos. And wait until after you have your suit to paint the mask.
3. Cut open the face.
When the suit arrives, you will need to cut out the face in order to see, breathe, eat, etc. Start small. You can always cut more out if you decide to.
4. What else?
You could leave it at that, but I wore some water shoes with thin green socks over them to keep from wearing out the feet. I also wore some seamless athletic boxer-briefs under the suit.
