When and how does Hermione end up naked?

Clothes disappear in the Forrest of Dean

After finding out Ron died, Hermione Granger needed to be alone. So Harry respected her Decision. It was cold outside lucky for her she was in warm clothes. Hermione was upset she the man she loves is dead, the other man she had an crush on was Harry Potter, before Cho Chang and Ginny Weasley stole him from her. Hermione walked an very long way from the camp, Hermione didnt realize her shoes disappear until her feet touch the cold ground, "Oh thats cold, hang on wheres my shoes and socks" said Hermione, She continue to walk away from the camp, Hermione was hoping nothing goes wrong, since it would be odd to walk back to the tent naked since the only person whos there is Harry. She deicded to explore the boundaries of sheild since Harry was the one who added it. Hermione was lucky she just lost her shoes and nothing that would make her covered herself.
