Alameda Antique Faire for $25.
The one I got is by Demetre and is very heavy wool in navy blue with red stripes and cool spiders on each sleeve.
You can find these vintage wool sweaters on Etsy or eBay, like this one with reindeer on the sleeves for $39. Or, this striped and somewhat nautical version for $23.
Meister and Demetre seem to be a popular brands of this type of sweater and a good keyword search on the vintage sites.
A little out of my price range, but beautiful, is the the Authier arm band sweater ($895) from J. Crew. This sweater is a modern version of the vintage 60's ski sweater. Made in Italy in navy blue with a red stripe at the sleeve it is sporty and elegant at the same time.
These would be great paired with skinny jeans and boots.
