Multiple Products..same old thing

Hi SEO Masters, quick simple question!

If you have a range of Tshirts.

All different colours/titles but pretty much only warranting the inclusion of a general description of the brand they represent.

Would it be bad for SEO, to have different titles but one general description about the brand on each product page? (i.e. Universal text about Sizes, Fabric and Brand/Product General information)

I'm looking to build a department store and so can't sit and make up 300 words of individual content for each single product.
