Big Sister Shirt for Girls I'm the Big Sister Which Makes Me the Boss Sibling Reveal Tee

Retro flower-power lettering spells out "I'm the Big Sister Which Makes Me the Boss" across the front, with playful daisies in pink, orange, yellow, and green. A funny, confident way for the new big sister to break the news herself — pregnancy announcements, hospital visits, and that first photo with the new baby.

• Sibling Reveal Ready: A memorable gift for a soon-to-be big sister from mom, dad, or grandparents — pair it with a matching little brother or little sister piece for coordinated photos.
• Soft 100% Cotton: 4.5 oz 100% cotton with a comfortable fit, pre-shrunk with a durable double-needle hem.
• True-to-Size Kids Fit: Classic unisex kids' fit with a crew neck and short sleeves, from 12 Months through Youth Large — size up for a roomier, roll-the-sleeves look. Check the size chart image before ordering.
• Durable, Vibrant Print: Professional-grade screen-printed graphics stay bright and crack-free wash after wash.
