Hey!! I am from Ireland and currently living in zakynthos which is crazy hot so I definitely appreciate well made and durable gym gear as I have to wash my gear on a daily basis!! I think I would be great for this job! reason one being that the gym is my second home, I am there everyday so I know what clothing works and what doesn't, what is practical etc, for example, when it comes to training tights or sports bras, i think it is vital to have a high percentage of elastine so the body will not be restricted etc. And for colors, styles, logos, I think a classic but stand out logo is always the way to go. Choose one that from the moment a customer sets their eyes on it they will be ready to purchase. You could also have a more baggy or free fitted line of tops for those who may not be so comfortable in tight clothing, or for those who are interested in the more relaxed look/style while training. For me personally, my tights and sports bra are always the core of my outfit and I think they should always be made of top quality materials, but also to have a fun option e.g a pop of color/cross over straps/keyhole design back etc, the list really does go on. If I were chosen to help design your gym apparel line, I promise I will give you 110% ! Thank you :)
