1) Makeup. If you aren't getting any male attention, 9 times out of 10 it's because you aren't wearing enough makeup.
2) Show some boob
3) Show some leg
4) Maybe change the way you walk if it's unsightly? Maybe swing your hips a little and wear small heels
5) Wear "feminine" clothes like skirts and dresses
Bearing in mind, there is no guarantee of the calibre of men you'll be attracting through these methods.
Alternatively, just go to a nightclub in full bombshell makeup. You'll still get attention with conservative clothing
