Such a cool custom find! This is a customized Lululemon Athletica red racerback tank top with the Gold’s Gym logo and “The Studio” on the front, and “Coach” on the back. It is a super lightweight material with micro mesh accents. This would be super cool for a trainer or member of Gold’s Gym! Size tag is cut, but looks like a small. Condition is reflected in photos, no flaws found on initial inspection.
