Benho, Yes Nature Bakery (Lor 27 Geylang, Aljuneid MRT) have a a few organic Tshirts. May be Yes Nature at Geylang Road is also part of Yes Nature Bakery.
Vivien, thanks for the reference. I will visit Yes Nature.
I am also trying to change to alternative clothing and accessories.
Please refer to my post "Vegan Shoes..."under General Discussions.
