Spacesuits - are not "clothing"- they are miniships. They can bring you into a world of missery, if they do not fit.

The truth is, if the mini-spaceship does not fit, you can not work properly outside. You can try, but you will fight more with the mini-spaceship, then with the task you should accomplish.
What fascinates me is how, they do not have a 2nd spacesuit up there if that spacewalk was planned that way. Nasa usually does not mess up logistics.
