Eve,

I think the couple in question were taken away because of the public display of affection but I would also say you are correct in that the woman drew attention to herself with style of dress which may have resulted in her being spotted during her PDA. 

Alexa - I choose to dress conservatively as well and am more comfortable in that style of clothing.  Of course I see women in less conservative outfits but like you I think its their life - let them live it.  Their dress doesn't affect me at all.

What a strange illusion it is to suppose that beauty is goodness.
