1. Toni's black shirt:

Where did the black shirt Toni wore in the bedroom come from. No one expected to stay overnight so no one would bring a night shirt. At several points earlier in the movie, you can see she wasn't wearing any black shirt.

2. The Sun Hat

The sun hat that Toni wore while walking is for women. Were exactly did it come from and where did it suddenly disappear to when they reached the mining hole.

3. Toni's bra

The bra that Toni wore leaving the mining hole was partial see through and the rest was full material. But when Eddy took her black shirt off later before they slept together, you can see the bra is now complete see through material.
