Is GOTS certification actually worth the marketing focus for a streetwear brand?

I run a streetwear brand in Boston, and we committed to strict GOTS (Global Organic Textile Standard) and GRS certifications for ALL of our products from day one. The upfront cost and sourcing difficulty were brutal compared to just using standard blanks.

However, we are noticing that our customer retention is significantly higher than the industry average. For those of you running or buying from sustainable brands, do you actively look for these official certifications on the tag, or is a brand's overall transparency enough for you? I am trying to decide if we should make the certification the centerpiece of our marketing this year or just keep it as a quiet standard we uphold behind the scenes.
