T-shirts by SG
Quality T-shirts and hoodies with clever phrases that make you smile. Every piece is designed to stand out and built to last.
Respect The T-Hoodie
In a city that moves on tracks and tires, respect should move just as far.
The Respect the T Hoodie is a tribute to the drivers, operators, and workers who keep Boston rolling every single day. Early mornings. Late nights. Snowstorms. Game days. They show up — and they deserve respect.
This hoodie isn’t just about transportation.
It’s about appreciation.
Respect goes a long way… like transportation.

About Us
For over 19 years, we’ve been proudly creating and selling classic T-shirts, hoodies, and hats that represent personality, culture, and creativity. What started as a small idea grew into a brand built on originality, quality, and the power of a good message.
At Seymore Green, we believe clothing should say something. Our designs feature clever phrases, bold statements, and timeless looks that people enjoy wearing every day.
Custom Printing
T-Shirts by SG provides custom T-shirts and apparel. Bring your logo or design, and we’ll print it on T-shirts, hoodies, hats, and more. Quality printing with fast turnaround.
Our Goal
At T-Shirts by SG, our goal is simple.
We want you to find a shirt in our collection that you think is clever, interesting, and worth wearing. A shirt that speaks before you even say a word.
Our goal is that when you wear one of our designs, someone stops you and asks:
"Where did you get that shirt?"
Because at T-Shirts by SG, we don’t make fashion statements.
We create statements that become fashion.
