Shoes
Now that I'm wearing trousers more, I don't really need to wear boots unless I wear a skirt or dress, or it's hot weather and I wear shorts (mainly because I think it looks better than shoes that don't cover all of my ankles and the bottom of my legs). So I had a look around some shops for some black trainers that have a decent grip. The best ones I could find weren't waterproof like I'd wanted, but I'll just have to live with that. It's surprising how many "black" shoes have white soles. No, I can't wear shoes with any white on them because they'll get dirty very easily.
By the way, I always prefer practicality when it comes to shoes, along with simplicity. Sure, I'd love to wear some cloppy shoes (shoes that go clop when you walk), but they generally don't have a good grip on them, and I'd rather not risk slipping if I have to run for whatever reason.
