People need to get over themselves and stop judging other people for doing their own thing. If you're not comfortable wearing bibs and jersey on your rides, fine, don't wear them. There's no law that requires you to do so. However don't go start knocking other people for wearing bibs and jerseys because it makes them comfortable. Society tends to build "norms" around every subject/topic that exist and people becomes a "sheep" to the current norm/fad. Wear what's comfortable to you, not what other people are wearing or saying. I used to wear running shorts and a T-shirt on my rides. However, it eventually became clear to me that my running shorts is getting in my way when I get back on the saddle and I need bibs. When I started bibs, I realized I need pockets to carry things. That's when I started wearing jerseys. After a while, I realized I was missing out wearing bibs and jerseys as they are a lot more comfortable to ride in.
