My Buying Guides on 100 Days Of School Shirt Ideas
When it comes to celebrating the 100th day of school, finding the perfect shirt can make the day even more special. Over time, I’ve explored many options and learned what works best for comfort, creativity, and style. Here’s my personal guide to help you pick out the best 100 Days of School shirt ideas.
1. Consider the Age and Size
First things first, I always check the size and age appropriateness. Kids grow fast, so I make sure to get a size that fits well but also leaves a little room to grow. For younger kids, soft and stretchy fabrics are a must because they move around a lot during school activities.
2. Choose Comfortable Fabrics
From my experience, cotton or cotton-blend shirts work best. They’re breathable, soft, and easy to wash — which is important when the shirt might get messy with crafts or snacks. Avoid stiff or itchy materials because kids won’t want to keep the shirt on all day.
3. Pick a Theme That Matches Your Child’s Personality
I love picking shirts that reflect my child’s interests. For example, if they love animals, a shirt with “100 Days of Roaring Fun” and cute animal prints can be a hit. Or if they enjoy sports, a “100 Days Strong” shirt with a sporty vibe works great. Personalizing the theme makes it more meaningful.
4. Look for Creative and Fun Designs
Some of my favorite shirts have clever puns, bright colors, or interactive elements like stickers or glitter. I’ve also seen shirts where kids can add 100 stickers or dots themselves, which turns the shirt into a fun activity. These creative touches make the celebration more engaging.
5. Decide Between DIY or Ready-Made Shirts
I’ve tried both buying pre-made shirts and making my own. DIY shirts give me the freedom to customize colors, sayings, and decorations exactly how I want. However, if time is tight, there are plenty of great ready-made options available online or in stores that are adorable and hassle-free.
6. Check for Easy Care Instructions
Since the shirt will probably be worn multiple times or kept as a memento, I always check how easy it is to wash and care for it. Machine washable shirts that don’t require special handling are my go-to because they hold up better over time.
7. Budget Wisely
I set a budget before shopping because prices can vary widely. Sometimes a simple, well-made shirt is all you need, while other times I’ve splurged on a custom design for a special keepsake. There are options for every price range if you know where to look.
8. Plan Ahead for Delivery or Pickup
Last year, I waited too long and had to rush shipping. To avoid stress, I recommend ordering or making the shirt at least a couple of weeks before the 100th day of school. This gives you time to fix any issues or add last-minute personal touches.
Final Thoughts
Finding the perfect 100 Days of School shirt is all about balancing comfort, creativity, and convenience. With these tips from my own experience, I hope you’ll find a shirt that your child loves and that makes celebrating this milestone even more memorable!
