I believe those are arm warmers - and the necklace, well, to my knowledge I don't really think it's a specific "thing", just the style of that necklace. You could probably look up something similar by searching "statement necklaces" to look at big chunky ornamental-type pieces. 

You could also look for knit gauntlets or fingerless gloves. Don't know about the necklace.

It looks like she has blue felt flowers on her necklace, something like [these on Etsy](http://www.etsy.com/listing/51528855/sale-fleurs-des-bois-forest-flowers?ref=sr_gallery_43&ga_search_query=blue+felt+flower+necklace&ga_view_type=gallery&ga_ship_to=US&ga_page=2&ga_search_type=all).

I don't know much when it comes to fashion and I couldn't find any pointers on the Internet as to the name of what she's wearing on her arms. Also, what are those blue things on her necklace?

What's that on her arm called? And other questions.
