What do you define as a lot of cleavage?
Whenever the top and the bottom of her breast are showing.
Are there times when you think a woman showing a lot of cleavage is inappropriate (for example: around children, at work, as a wedding guest)?
Anytime that flirting with said woman would also be inappropriate. Esspecially since when a gal shows off her cleavage, she's flirting with every in line of sight of her.
Do you form an opinion of someone who is wearing a top that shows half of her boobs?
Well, we can't help but form an opinion of someone in the first 5 seconds that they have to make a first impression. I do find it funny when she complains that everyone is staring at her
How does everyone else feel about cleavage???
(see previous questions)
