T-shirt or t-shirt

Sorry, but neither.
It's T-shirt.
Having said that, what do so many people write?: t-shirt
So take your pick!

You mean T-shirt should be the right one, but it is not wrong to use t-shirt?

Hi,

david.healed T-Shirt or t-shirt, which one is correct?

T-shirt or tee shirt.

Regards

T-shirt is formally correct, but whether a T-shirt, a t-shirt, or a tee-shirt, do you think most people are going to care? Remember, advertisers often perk up spelling to make their product stand out, give it a buzz: using 'nite' for 'night' etc.
