No, I'll call. BUt when I posted I didn't have time. Just seems like common sense to specify what exactly a wool-blend sweater is blended with. Having to call or email is just an unecessary step if you want someone to part with their money (especially on a whim).
No worries. We like feedback and I agree with yours. We're working towards better descriptions for product on the site. In most cases we suggest sizing up or down when necessary, otherwise you can assume an item is true to size.
