Depends on the environment and on what I'm doing. It's about 19C/66F now, and I'm comfortably indoors at the computer. Our kitchen/dining area is outdoors; I never wear clothes to cook breakfast, with predawn temps here running down to 12C/55F, but if it's below about 16/61 I'll put something on when I sit down to eat. I went to college in Michigan, where in the spring students would sunbathe on the sunny side of tall dorm buildings while the snowdrifts were still melting in the shade.
I can tell you from experience, temperature tolerance is a very relative thing. When I was in Iceland, anything above 32F with the sun shining (and no wind) was summer. I once laid out on a picnic table with the high that day only 32F. When I was in Saudi Arabia, anything below 100F was "nice" until it got below 80F, then the jacket came out. If it dipped below 70F, the coat came out.

Everybody is different. Just because some people can't tolerate cold weather, doesn't make them a "wussie".
Agreed what's the point in being uncomfortable. 10c = 50f, with no wind and sun that can be just about OK but any lower or a chill wind and so much depends on what you are doing. Working or exercising hard you can be comfortable at much lower temperatures than you would be sunbathing or just pottering.
Running out of a nice warm sauna into a chill pool or cold shower is simple masochism and if not doing that makes me a "wussie" then I'm happy to be one.
Nope, some just prefer to be comfortable. When our pool temp dropped to 72F, it was good to ice up my foot prior to surgery and that's about all. Yesterday was 81F here yesterday. I know what COLD is, I grew up in Long Beach, LI, NY and suffered ice and snow. Moved to Tulsa, OK where there was cold and ICE. Living in the South Carolina Midlands is the only place that really feels like home to me.
