Welcome to tFS, claudiaz (since this is your first post). I'm John. Nice to meet you.
So you're sporting that Timberland Ivande oxford? I would instantly say some dark blue (but not too dark) denim jeans. I think you have to wear something brown to stay consistent with the shoe's design. However, I think you can go with some kind of beige or tan pants, mostly with a regular leg or even with a bootcut or wide-leg design. Best go to go with a casual look. Of course, beige or tan jeans with voluminous legs wouldn't hurt either. If there is an uncommon look I've somewhat been drawn to, it's pairing oxford shoes kind of like that (I'm thinking more along the lines of the Skechers Minuet or Grand Jamz sneakers) with proper office wear slacks. These shoes are too casual to even attempt this, so I'd avoid this.
I'll leave it up to you to find out what kinds of tops and/or outerwear to wear with this. Either a denim jean jacket or some brown jacket would be a nice accessory with those shoes. I'm thinking T-shirts as far as what top to wear. Either a T-shirt or some polo-type shirt.
Another option for bottoms would be some kind of denim skirt. Depends on either a denim mini or some full denim jean skirt. Your call. That's how I'd wear these.
