/cgl/ - Cosplay & EGL

I'm looking for 3 specific but hard to search for things. I'm looking for cut-out sun dresses, those odd type of necklace things that I don't even know what to call in english and partially see-through tops. I'm basically just trying to figure out how to say "cut out", "transparent" and whatever I'm supposed to say for whatever those necklaces are. I checked the dictionary but didn't see anything for any of them.

If any of you know what the proper chinese phrase for these or know of links to the types of itmes themselves, I would be super grateful!
