I have a thing for uniforms.
Uniforms are seen in negative light in America. Conformist, working for the man, the tie being a leash and a noose all at once. One of my first jobs was at Target and I loathed the daily khaki pants and red t-shirt getup. I later sweated in wool suits in the middle of summer as a car salesman. Police and armed forces, on the contrary, wear uniforms with more pride because let's face it, they're badass in uniform and they have lifelong camaraderie with their colleagues. In the case of Target t-shirts and the stripped-down uniforms of tech and retail, I believe the American anti-conformity contributes to their being less cool than they could be. These companies need to 1) help people to love working there and build a sense of family in the work place plus 2) create uniforms with fashionability and comfort as a priority. Make them so cool they wont not wear them.
Make your work shirt your favorite shirt.
Japan has a thing for uniforms, too. It was heaven for me. It seemed that literally everyone who was on the clock had a very clean, well-kept, and beautiful uniform. From the oceans of business men in black suits and ties, to the cartoon character-esque ribbed white gloves worn by train conductors and crossing guards, the simple yet sharp uniforms unique to each school, and the ornate badges and details of all, it seemed everyone had something awesome to wear. The Japanese are very well dressed regardless of employment, and I felt like a slob in the t shirts and nylon pants I wore the whole trip. I don't think this makes the Japanese conformist, no. They do everything to 100% there and dressing for work to play the part is one of those things.
Following a culture based in ancient traditions of micro clans spread throughout the archipelago, each with their own tight-nit communities, castles, and gathering places, there is a strong sense of family and loyalty in whatever one's 21st century manifestation of a clan might be. The field of organization theory calls this Theory Z, which suggests a healthy organization has managers who lead as visionaries, allow staff to experiment and be creative, to cultivate a familial, clan-like culture in the office, and to foster lifelong loyalty to the organization through a connection to it's overarching mission. While times are changing and Japanese companies aren't seeing the loyalty the used to, the culture remains and loyalty to one's clan remains an aspiration for the professional lifestyle. Theory Z has been adopted by American tech companies with mixed results. Maybe it comes down to the apparel.
