I agree with Versalis here that any decent seducer, especially during day game, should be well aware of those approach invitation cues from women so they don't waste their time getting burned a lot rejection after rejection from women who don't want to be approached.
Personally, I don't give any woman my attention until she has earned it. She has to earn it by hovering around me within 4 to 6 feet, passing by back and forth at my line of sight, talking or laughing louder when I'm around, opening me with some lame girlie opener like "Happy Birthday," "Guapo (handsome)," "Snob," or "Derek Ramsay! Seriously, you look like Derek." and giving me at least three strong IOIs (eye contact and then looking down at the floor, preening gestures, and stealing glances at my cock area [damn, put shiny things near your fucking cock and your attractiveness shoots up through the roof]). It's easier this way and sets the frame that you're the prize.
When I'm in the mood though, I just cold approach anyone and railroad ahead, IOI or no IOI. It's harder this way but you become sharper with your sexual escalation skills.
Btw, any decent seducer should fix their hygiene, grooming, masculine fashion sense, and health with good regular exercise and seduction won't be an uphill battle.
