Writing product description for sustainable men's underwear

Hello!

BLUEBUCK is a brand of sustainable underwear, Tshirts and socks for men, which I founded 10 years ago. Products made with organic cotton or recycled fibers, production 100% European, made with renewable energy, only permanent collections. A brand description can be found on the attached PDF (the texts are more up to date than on the website which is www.bluebuck.net). I am currently working on a new website and I want to rewrite all product descriptions.

To start with, I would like to work on the briefs and the trunks from the 2 organic cotton collections (Classic and Nautical). The briefs and the trunks have the same shape and composition, only the colours change (plain colours or with stripes).
I would like the descriptions to be as different and unique as possible, to avoid duplicate content. (I was told that ideally, 75% of each product description should be original). I prepared a list of over 300 keywords and ideas that can be used - you will find it attached. This list is not exhaustive, you can of course add to it (synonyms and your own ideas). Each description will be between 50 and 80 words approximately.

I also started writing a few product descriptions for briefs (5), which you will find attached. They are just examples and can be improved (English is not my first language).

Regarding the tone: I would like to keep the texts relatively informal, not too serious, with a touch of humour when possible (the current texts on the website are not humorous at all... but the Instagram posts are trying to be a bit funny @bluebuck_adventure)

Beyond this job, there will be more in the short term and in the future: for more production descriptions (some more underwear, also Tshirts, socks, swim shorts, all made with organic cotton or recycled fibers) and for more in-depth articles about sustainability, about the brand commitments etc. that will be posted on the home page, as well as various articles for the blog.

Any interest and knowledge about sustainability (in fashion, climate change etc.) would be a plus, but not a must.

Any questions please message me

Thank you, looking forward to receiving your proposal!
