Yes Priiin! Thats where I first saw them then. I was racking my brain, I thought it was from a picture I saw in People magazine or something like that but in one episode LC did hold up the eternity shawl when shopping. I just rewatched that episode of The Hills. I think I watch the Hills for its fashion more than the enjoyment!
I received an email from Kataphileo.com sometime this past weekend..I posted it in another thread..anyway here it is Kataphileo.com has the grand pleasure of being able to bring to you:
Suzanne Juul's “Eternity Shawl”
For those of you unaware, the “Eternity Shawl” is the must have accessory of the season! Seen on celebrities such as Mary Kate Olsen, Eva Longoria, Hillary Duff, Britney Spears, and the list goes on and on! Rumor has it a store in L.A. is awaiting a shipment to arrive today (Dec. 14th) with celebrities such as Paris Hilton waiting to snatch one up. The store would not disclose to Suzanne Juul any other celebrity names due to confidentiality. You better buy this one up quick before its gone!
