To keep your celebratory Graphic Tee looking fresh and vibrant:
- Machine wash inside out in cold water with similar colors.
- Use non-chlorine bleach only when necessary.
- Tumble dry low or hang dry for best results and longevity.
- Cool iron inside out if needed; never iron directly on the printed design.
Does this shirt run true to size?
Yes, this unisex shirt features a classic fit that generally runs true to size. We recommend checking the size chart if you prefer a more oversized or tailored look.
How durable is the graphic design?
We use high-quality DTF printing, which bonds the graphic deeply to the soft cotton fibers. When you follow the care instructions, the bright design will remain vibrant through many washes.
Is this a good gift idea for a brother to give his sister?
Absolutely! While the shirt is primarily worn by the sibling celebrating the birthday, it makes a hilarious and thoughtful gift idea from one sibling to the other, especially if they are attending the party together.
Is the fabric thick or lightweight?
The fabric is a mid-weight, soft cotton that provides excellent breathability, making it comfortable for both indoor parties and outdoor casual wear.
