A good place to purchase matching slippers and socks would be from online retailers. Amazon offer a good range. It would be quite difficult to find matching slippers and socks on the high street.

Pull out three socks. You will have at least one pair that matches.
In order to get a matching pair, you must take out a minimum of two and a maximum of three socks. Reasoning: The question does not specify a color for the pair of socks, it just asks for a pair of matching socks (same color). Hence, the first sock you pull will be either red or white, and the second sock you pull will also be either red or white. If the second sock matches the first one, you have a matching pair (reason for my "minimum of two"). If the second sock did not match the first sock, then you have one red and one white sock. The third sock you pull will also be either red or white and you will have a matching pair of either red or white socks (reason for my "maximum of three").
Many stores that sell clothing also offer socks that are lime green in color. The Nike Shoe Store is a good place to find lime green socks. Also Famous Footwear sells lime green socks.
100% She will either have at least two brown socks or two white socks in any scenario.
