we haven't seem to move on from this. Just wear what you're comfortable in. If you're concerned about shape showing out from tights, just wear something under. I read in some forums ago, runners wear underwear, some also suggested a dance belt" to be a good alternative as it works for ballet dancers in white tights!
I wear skins half tights during summer, 2xu long tights during winter. I recently bought the Nike Swift Gyakusou range which has very cool designs. I wouldn't want anything over my tights when I invested £100 on it.
Why would anyone be so conscious of how they look in the front when they are running? Spectators would only have a glimpse of you for 3-4secs when you run pass them. I haven't come across anyone running in front would bother looking behind just to gawk at your front. Anyone who does has a different intention from running.
