Thanks so much for your reply animats, i was so sad noone was helping.
by the way i resolved my problem alone, maybe it will be interesting for someone else ^^
I don t know how but, all the items i was wearing went double, i mean i was wearing everything twice, 2 heads, 2dress, 4earrings ... everything was double .... then when i tried to wear something i was " full" of attachment that s why i couldn't click on add or wear ^^
i have detached all and attached what was needed ....
strange experience ^^
