The only appropriate answer to this question in my opinion is white cotton panties. I do not care if thery are bikini, or hipster, or briefs, but they had better not be thongs!
Be aware, if you are being spanked by Veronica Daniels, and you are female, you will recieve twice the normal spanking if you show up in anything else!
And, yes, I feel that strongly about it!
Happy spanking-
Veronica
