I was looking at some silk and cashmere blend sweaters at Banana Republic the other day and was wondering if anyone had any experience with them. I think they are 85% silk and 15% cashmere. I know BR isn't known for the greatest quality but I'm in college and can't afford much much. I think they would be nice to wear as a lighter weight layer. Also, can they be hand washed? Their site says dry clean only but I'd rather check here first.
