Clothing in Spaaaaaaace!

[nondescript handle]

Unless you'll have very exotic places like the smoke ring from Niven's Integral Trees, all environments with free fall will also be totally temperature controlled. On todays ISS basically everyone wears polo shirts.

I guess I can see full arm shirts for a space navy mess dress or stewards of interplanetary luxury liners, but I have a hard time envisioning multi layer clothing (e.g. a toga over form fitting clothing, a shirt under an uniform tunic) in such a context.

My guess would be that informal civilian dress in a shirt sleeve free fall environment would be something like (not too loose) shorts and T-shirt (worn inside shorts) and bare feet.

For people for whom EVA is common (e.g. the SF cliché of the "belter" miner), an "undersuit" might be typical "inside" clothing (and designed to be worn as such).

I don't think that a spacer culture will routinely wear emergency gear for decompression. If decompressions are that common that you'll have to wear such things, it will not be a "culture" but a frontier were experts spend limited time in.

I mean most of our earthling homes are flammable, but most people don't wear fire extinguishers...
