20 Distinctive 100th Day of College Shirt Concepts

Reaching the 100th day of school is certainly a milestone that should be celebrated! Although dressing as a 100-year-old is a popular way to celebrate, so is designing or donning a shirt for this special occasion. Regardless of whether you’re a crafty do-it-yourself type or an add-to-cart type, we have you covered. While DIY options can be intricate enough to break out the old Cricut, some can be as simple as sticking stickers on an old T-shirt. The store-bought options are great too since they come in a huge range of styles and sizes. Check out our list below of the best 100th day of school shirt ideas!
