Plus Size Milestone Birthday Shirts: 40th, 50th, and 60th

Milestone birthday shirts for plus size women are in high demand and underserved by most generic shirt vendors. The big-box options typically stop at XL or 2XL. Bear Grips Pro Shops offers plus size milestone shirts up to 4XL at the same base price as standard sizes.

For a 50th birthday, the Airlume Cotton Athletic Tee in a dark color (black, navy, forest green) with a clean '50: [Birth Year] to [Current Year]' design is one of the most popular plus size milestone shirts ordered through Bear Grips. It photographs well, feels soft, and is wearable beyond the party.
