T-shirt time!

If you’re an elementary-school student with a knack for design, it’s not too late to enter a T-shirt-design contest sponsored by P.S. from Aeropostale, a chain of casual apparel for kids ages 4 to 12.

In the P.S. from Aeropostale “What Makes You Smile?” contest, students submit a T-shirt design based on what makes them smile. Entries are due Wednesday. Contestants’ families and friends can vote Nov. 1-15.

The top 100 designs with the most votes become finalists. Judges pick a grand-prize winner from each grade. The prizes include a $500 store gift card, $1,000 for the winner’s school, a celebratory school presentation, T-shirts for the winner’s classmates and 50 T-shirts displaying the winning design to hand out.

Winning designs will be announced in December. Enter at pswhatmakesyousmile.com.
