It's not just size, either, getting a bit more muscle, depending on your body type, can look more impressive than it is.
The other day I was going into a local gardening center and had on a slightly tight shirt, when I got to where some people were waiting in line, even though I had room to get by easily, they moved aside more to let me through.
