That shirt you linked to is great. I have worn that to the night clubs; just a push up bra and a lil’ black camisole. We are talking major, major cleavage. But in the reggae clubs, it is normal for the ladies, both large and small, to expose plenty skin.
I also want to say to big girls with big busts that a belt is great. it shows off my ‘waistline’ and really showcases the figure. With a tight pair of jeans and stilletto heels, Woo! I love it!
