Greetings,
Sorry to disagree Tarv, but I've kitted myself out in not bad gear, advanced several tradeskills to 200 and 2 over that, plus still have about 170k in the bank - all from tailoring! And this without doing any PoP tailoring.
Acrylia studded sleeves I can sell up to 4 sets overnight, every night, at 600pp per set. Acrylia reinforced boots and gloves also fly off the shelves. I've sold about 75 Fleeting quivers at prices between 2.5 - 4.5k each. Cobalt drake belts and Black/Haze Pantherskin armours are also regular sellers.
If you want to make heavy amounts of platinum, I'm sure you're correct Tarv. But being a casual gamer, I'm quite happy rolling over my modest profits and investing some of them in the pursuit of that elusive 250 Tailoring skill! Ginerdar, I'm no expert on DE tailoring, but you CAN make money at it - you could probably make a fortune just selling leather padding at 40pp per item - and you may find that there are DE-only combines that you can turn a nice profit on.
Hope this helps!
