Such has been the impact of Y-fronts that they have become a universal shorthand for men's underwear over the years although none of the competition have the upside down 'Y' seam which gives the garment it's name. The fork of the Y frames the pocket in which the male organs rest in a most satisfying way.

The shape and size of the pocket varies, small ones creating a 'trapped' effect while broader styles bring the area forward visually.

The other salient feature, traditionally, is the high waist which looks a bit old-fashioned in this day and age – but in a way that's part of the appeal, suggesting an innate modesty in their wearer which is endearing. The wearer is no flashy kid, but a mature adult who favours comfort over image and who expects to reveal his underwear only to the select few.

Modern Y-fronts however do make concessions to the trend to skimpier fits and this picture shows a lower waisted example which is by no means short on erotic appeal.
The superman tattoo on this model makes a nice connection to the heyday of Y-fronts in the 50s and the joke about wearing of underpants outside his tights.
