Air travel has certainly changed over time, and what was once an occasion where smart dressing was mandatory has become significantly more casual.
Recently, Spirit Airlines issued a new dress code for its customers, after several news reports about customers being removed from flights because of their clothing.
Now Spirit Airlines customers can be removed from flights if they are “barefoot or inadequately clothed (i.e. see-through clothing; not adequately covered; exposed breasts, buttocks, or other genitals), or whose clothing or article, including body art , lewd, obscene or offensive in nature.”
