Hopefully someone here can explain what's going on to me. I tried to unlock the tiki chic achievement, which says to wear "pink level 70 tiki helm, armor and weapon". Mine didn't unlock even though I've worn all of the following sets:

Feather headdress of tiki
Tiki malo wear of tiki
Beach bum's bow of tiki
Double tiki shanks of tiki

Crafted str set (tiki god's sand walker stuff)

Crafted dex set (tiki god's sand skipper stuff)

All of the above are level 70 stuff of course. Exactly what "tiki" stuff is it expecting me to wear??
