Answer:
I am personally quite happy that lariat necklaces are coming back into style.

Try http://www.etsy.com the products made there are mostly made by artists and hobby designers. The prices are great for most items. Some will even do a custom piece for you if you give them ideas/specifications, which would make the gift that much more romantic.

Answer:
Go to a store that she likes to purchase clothes at…like express, macy's etc. Even Target sells adorable things and they’re usually reasonable. Payless Shoesource usually has a lot of new items at a GREAT price too!
