Except the clothing is intended to be worn on people, so how can you judge if it will actually look good if you design it for aliens? It's like car designers intentionally doing all their drawings such that only 3' midgets can use the car or furniture designers intentionally drawing things out of proportion to the human form. The purpose of sketches is to develop and test ideas before a prototype is made, but if you have to completely rework the proportions between sketching and prototyping then the sketch is worthless for the purpose of judging the aesthetic appeal of the design. It is like the entire fashion industry is in denial about what medium they working in.
A comment well deserving of a beer. Lets not also forget the intended purpose of a space suit. Their needs to be room for tubing for Air, cables to check vitals and ports to connect into other systems I am certainly not aware of. There is a reason why space suits look the way they do now. Watch the end product look just like the current model but with a pink sash over it.
Never ask two questions in a business letter. The reply will discuss the one you are least interested, and say nothing about the other.
