I have some Pactimo tights without chamois that I wear over bib shorts. In this area we can have wild temp swings . Leave home in low to mid 50's and get home in mid 70's or worse. The tights roll up small enough to put in a jersey pocket if I get too warm on the ride.
I tried leg warmers and didn't like them. Couldn't find any that would stay put.
I don't worry about what I look like on the bike. Non-cyclists will think you look ridiculous no matter what you wear. Other cyclists won't care. Wear whatever makes you comfortable.
