Here’s a sure sign that cooler weather is on the way: Sheepskin Gifts & Alpaca Too, a seasonal tenant at Westfield Montgomery Mall, has returned for the winter in a new space next to Brookstone. The store carries a surprising variety of gifts and clothing, from sweaters, shawls and coats to hats, gloves and boots for adults and kids. (Biggest draw for men: the sheepskin moccasins with gel soles, priced at $69.99).
