In 2021 the simmer ashubii started a thread by this name, which served as an inspiration to several of us. Now like many other threads the screenshots did not get transferred over, nor did it en...
The 1910s were dominated by WWI and the effects of the war and this is true for fashion as well as anything else. This means that the war itself means a shift in fashion so that the first half of the decade is more like the previous decade and the last part is decisively different. A slimmer silhouette, a military influence on cuts and material and darker colors (quite common in rough times) are some of the things that effect the time.
Working class men:
Yet for working class men not much happens fashion wise. In general you can keep using the clothes from 1890s for this group. In general the fit is poor and lose, suspenders and belts a necessity and the three piece suit a staple. Pants were rolled up at the cuffs, jackets had deep pockets, colors were dark and fabrics durable. For the sake of variation I have added a few new options all the same.
The first two are as examples of suspenders and work wear clothes (after the jacket is taken off), the two latter a representation of the increasing popularity of knitwear.
Middle and upper class:
While there was a definite difference between middle and upper classes in real life, it's harder to maintain in game. It's more a question of quality of fabrics and fit than a difference in clothes per say as the middle class would always try to imitate the upper classes. When it comes to men fashion there was also less changes than for women, and the previous decades still work (especially since we have very few option of representing the new military style of wardrobe. Neither jackets or suits has any good options for this). You could add one of the more modern suits to gradually show the changes, but to be fair there isn't so much you can do with this decade when it comes to men.
The summer options are a bit better. Here I have tried representing the new fashion with rather short pants that showed off the socks (which could be quite colorful). For winter I just replaced the hat with the new fedora which was starting to come into style (although it looked quite different at the time, it was still the start of the hat we know from later decades).
For formal wear there are bigger changes as the tuxedo started to become a popular alternative to tails. I've added two options here for the new and modern man:
