Dear Mr. Throup
While I appreciate your design approach, I don't know that your clothes are functional enough for the needs of the average wearer. Shirts, for instance, could be improved with a liquid resistant spill bib and refillable pouches in the underarms where the user can put baking soda or charcoal so that deodorant, and indeed even washing, aren't needed. On outerwear, by the cuffs on the top of the arm, I would like to see a pad in a dark, soft material that's useful for absorbing liquids issuing from the nose and mouth, as well as a Swiss-army-knife-like attachment on the underside containing a fork and a spoon so that I don't have to find, or even hold, utensils. Skull bags should be lined internally in insulating plastic so I can simply pour my lunch into my bag and then use aforementioned sleeve utensils to eat it. Pants would be dramatically improved with a system in which the whole seat of the pant is lined and leads to a small, discreet tube running down the leg that opens near the ankle, allowing the wearer to casually empty liquid contents while walking.
Your designs unfortunately lead me to believe that you just haven't put that much thought into them, and that perhaps you should spend a little more time perfecting your products before rushing them to market. On the upside, a more considered approach might allow you to charge more as well, as the customer would know he's getting a fully thought-out garment rather than something hastily and thoughtlessly planned and assembled. I hope you'll find this criticism constructive.
