Sister Thrift is a cozy, clean, and small thrift store that is not overwhelming. It is a great hole-in-the-wall place with a decent selection of random stuff, vintage items, and cool momentos. Shoppers can find hidden goodies and amazing holiday decor. The store donates its proceeds to animal shelters, including the Metrowest Humane Society and the SPCA, which is a good cause. The same longtime, friendly staff make the experience feel like a dose of self care. It is a go-to place for donating higher end, gently used items.
