MartinPatrick 3 will welcome Minneapolis-based apparel line My Sister to its prestigious sales floor this week. It’s a big deal for a small independent company, to be positioned among brands such as John Varvatos and Missoni. And it’s a social statement for the Twin Cities’ preeminent men’s store: My Sister, known for its messages of empowerment, donates a percentage of proceeds to organizations that fight sex trafficking and help victims recover. MartinPatrick3 will give 100 percent of sale proceeds back to My Sister. “By doing this, they are making a great investment in raising awareness, funding after-care programs and employing survivors,” says My Sister’s co-founder Wayne Zink. My Sister works with organizations both local and global. MartinPatrick 3 will sell the full men’s line, which includes shirts and accessories. Look for My Sister at MartinPatrick 3 starting Thursday, Feb. 25.
