How can we as a group create an identity for a store brand and two private brands?

"Creating a retail store that competes with Williams Sonoma, Crate & Barrel and Restoration Hardware and specializes in products for any home. In a group, we designed a package for each category by creating a main store and private brands.

Ethos have three categories: Live, Prep and Essentials. Ethos Live is the core of the store striving to make good contemporary design available through a selection of timeless and functional products. Ethos Prep is a brand of high quality tableware products, that is responsible during the production and environmentally conscious. While all Ethos products are made t0 last, the idea of Ethos Essentials is to ensure that the cleaning products work for home and improve the environment at the same time.”
