A multi colored plaid long sleeve shirt and black ripped skinny jeans are an easy way to introduce extra cool into your current casual routine. A trendy pair of dark brown suede chelsea boots is an effortless way to add a little kick to the look. If it's one of those bleak autumn afternoons, what better to cheer it up than a on-trend look like this one? As you see here, in your 20s your sartorial options are in no way limited.
