Son of a!...I can't find this style *hisss*

Yes, well... there's this old style of dress that i'm fond of but I can't seem to find the name of the thing. I would assume it's from the 1800's but what era? Most of what I've found is far too decorated. Maybe this style only shows up in fairly tales?
Thus far I've seen it in numerous pices of art and a few fairlytale books.
If anyone knows the name of this style of dress please let me know! I'll love you forever.

Example:

maybe do a search for fairytale dresses and such...I've always had some luck with just typing in a certain style.
