Mens summer fashion is very plain, but there's a lot you can do with layering in winter. And you can wear different fits of trouser and t shirt. Flared or pleated trousers, ringer t shirts, etc.
This is an open call to all men, buy yourself a pair of well fitted non stretch denim straight leg jeans. A secondhand pair of levis. They are fucking everywhere. They will go for less than £20. They will last you many years. They will make you not look like a tool (sorry modern communists, you have the worst dress sense). They will make any t shirt you wear with it look somewhat styled.
