Hey guys

I'm doing my first tshirt shop in commerce and I wonder how to make an item without variations, but when you open item on product display site there is an option of choosing color, size,... in the form of simple drop down list. I think that making of so many variations can take very long time and also in my case price will be same for all items regardless of color or size of t-shirt so I do not need variations. I just need information on the properties of t-shirts that customer wants that it can be done according to his wishes.

Thank you very much in advance for any answers, advice and guidance
