If there's one thing kids born in the 90s like to do, it's reminisce about the fact they were born in the 90s, making the 90z Internet Child Tee the perfect fashion statement.
Wearing this shirt will cause you to fondly remember the days when you had a WIndows 97 desktop and still used dial-up internet. Though you would never in a million years trade in your macbook for one of those archaic machines, it's still nice to indulge in a little old-fashioned nostalgia from time to time.
As an added bonus, the shirt will advertise the decade you were born in for everyone around you. Make sure to preface it by saying things like, "You'll only get it in you were born in the 90s," followed by conspiratorial laughter.
