Hairy Baby is an online store that specialises is selling graphic print t-shirts and hoodies for men, women and children. It is an Irish owned company and it is very successful. When shopping you choose what you want your shirt to say, theres a wide range of options to choose from. Most phrases appeal to the Irish audience extremely well as they are mostly local slang.
I can take a lot of inspiration from this brand as it is very similar to what I am thinking about doing for my FYP. I think this site will be a great point of reference.
