Belly Shirt Season 

Belly shirt season is the single most best season of the year. It occurs around summer/spring time. The best and most respected part of this season isn't the weather, however; it is the women. Women around this time wear shirts also known as crop tops. Women who are fit and attractive really are the stars of this season unless you are a chubby chaser which is fine too. But the main ideal preferred women in a belly shirt has little fat and a perfect tummy that really turns men on sexually. Belly shirt season mainly occurs in summer/ spring time because it is too cold in the winter to wear this kind of apparel.

"Oh gee golly, belly shirt season is going to be yummy as fuck this year."
