How does Meredith Masony’s 'It’s fine' shirt design outperform other mom-themed apparel?

When I look at the “It’s fine” shirt compared to a lot of other mom-themed apparel, a few things make it stand out:

• The phrase is short, universal, and instantly relatable. Every mom has said “It’s fine” while absolutely nothing is fine, which makes it funnier and more wearable year-round, not just on holidays.
• It isn’t overly cutesy or decorative, so moms actually wear it with jeans, leggings, or under a cardigan—real-life, school-drop-off friendly.
• It captures the exhausted, honest, Filter Free Parents vibe instead of the “perfect mom” aesthetic, which builds connection and community, not just a cute look.

What kind of mom-themed shirts do you usually love (funny, sentimental, subtle)?
