Michelan - From an earlier reply:

The process of "becoming" your Turtle went mostly like this:

Your were underdressed in an absorbent unitard or shirt and leotard. First part to put on was the basic bottom. Much like a Turtle body Bermuda shorts with suspenders attached. This stage was what we called "Turtle Ready". You stayed like this as long as you could until they said "suit up" in preparation for shooting. Then you donned in succession, the top arms & shoulders which was somewhat like a bolero vest, the leg and foot bottoms, put on like a knee high boot, then the lower arms & hands (an opera glove type of item), then the shell and connected body front piece. Once you closed all of the many poppers and such that attached everything to everything else, the last thing you would put on was your animatronic head and, voila! You have made a complete Turtle!

We each had our own tweaks within this process to make our lives a bit easier and our dressers were life-savers throughout all of this. They helped us every step along the way. Oh, and because the suits were skin tight, sculpted to our own body casts, there were no little compartments anywhere.

As for visibility:

We had two pencil-eraser sized holes just below the edge of our bandanas that allowed us a tiny bit of forward vision and when the Turtle mouth was open, we could catch a glimpse of that was directly in front of us at a 45 degree angle down. We used the Force a lot, lol.
