I think these two assets are identical--looks like an accidental double upload:
http://www.makehumancommunity.org/cloth ... shirt.html
http://www.makehumancommunity.org/cloth ... irt.html_0
Aside from being redundant, this duplication creates problems with the community assets synchronizer--a problem also seen with one of the hair materials, unless that's been fixed since the last time I remarked on it.
