Not all nipple slips are created equal. There's the drop, the drag, the slide, the shimmy, and the peek-a-boo. I think I'd categorize this Frankie Sandford nipple slip pictures taken outside the Chinawhite club under 'the slide', a nice glimpse into the top of this Saturdays singer, who may be behind Una Healy (for me) as to hot Saturdays, but whose nipples I will gladly gladly ogle all day and into the night. I'm keeping my eye on these Saturdays girls. Enjoy.
