Leader Antenna - classification: headphones, 80 SG. The item color takes the color of the outfit/outerware.
Ursula Replica: Shadow - classification: female all race outfit, 400 SG. Probably, we'll see some other color variations...
Flapping Hawk: White - classification: necklace, 160 SG. The item color doesn't change. We've already seen Flapping Hawk: Brown and Perched Hawk: White. So, probably the next one is Perched Hawk: Brown.
Cosmos Hairpin: White - classification: headphones, 80 SG. The item color doesn't change. Couldn't find a good image for this. Please look here for the pink color variation of this item.
That's all, see you next time!
@samplexample I'm not sure. At least, it's not on this thread.
