Your togs are your clothes. If you're running late in the morning, you might have to throw on your togs and skip breakfast.
When you leave the house and find it's much colder than you realized, you may want to run inside and put on warmer togs. And if you have soccer practice after school, don't forget to bring your gym togs with you. These days we only use the informal togs in this plural form, but tog once meant "outer garment"; it was shorthand for togman, "loose cloak," in thieves' dialect.
