Which case should I get for my iPhone 6?

Between these three options which one should I get?:

a) the sulley_1 from http://www.ebay.com/...0550756961" class='ext_link'>http://www.ebay.com/...0550756961
b) the blue ear stitch from http://www.ebay.com/itm/331360255729?var=540550756961
c) http://www.amazon.com/...00Q1GHF2I/

The blue ear stitch.

Don't you think your iPhone is very nice without any cover.

I think you should get the Sulley one. It's cute and the least bulky
