any information to share about shirt accessories for men? such as sleeve holders, cufflinks, collar stiffeners, etc?

i think the long sleeve shirt is an essential part of any man's wardrobe. i love long sleeve shirts, especially from thomas pink. but for now, all i can afford is topman and esprit =(

one more thing that i'm looking for is sleeve holders. i usually fold up the sleeves of my shirt, but they never stay where i want them to stay. any idea where i can buy some sleeve holders to keep my sleeves from getting in my way?
