I remember watching womens touch rugby on tv decades ago and remembered them wearing skimpy outfits, It's taken me all these years to find it on youtube but this is sorta what I remember seeing. They are basically wearing what athletes wear in track and field or diving or old school swimming, but in a rugby context it looks skimpy and a tad odd. This should have been a more popular tv sport. The rugby 7's girls should wear these outfits. Also found a few amateur vids, two of them wont embed for some reason.
