How to interpret "A women who reveals her body or even wears tight fitting clothes wont come within 500 years of the smell of Jannah"?

AskImam quotes the Prophet as saying: > A women who reveals her body or even wears tight fitting clothes wont come within 500 years of the smell of Jannah. and the extended version > Women who are dressed but appear naked, who will be inclined (towards men) and make (men) incline (toward them). They will not enter Jannah and they will not smell its fragrance where as its fragrance can be would be smelt from the distance of 500 years. I'm struggling to understand this. In particular: - Am I correct in understanding that this is a quote from the Prophet Muhammad ? - Does this imply that (believing) women who dress immodestly throughout their lives without repenting will not go to heaven? If so, where do they go? - How much of their body is required to be revealed before this applies? - What does "smelt from the distance of 500 years" mean? Distance is not usually measured in years, nor is it smelt.
