Serge Marck's Ludivine outfit has socks, and fits the standard PT -- seems to be currently at Valentin's aka http://valentin3d.free.fr/characterskids.htm but some of the links are broken. The TentenJ sailor suit outfit has socks --- look under Project, Tenten at http://iso.power.ne.jp/ Presumably will need a little re-scaling but they are also free.
