I have had good luck with Freya, Wacoal, and Parfait. Freya and Parfait I believe are from Europe. Freya has a lot of bras the way up K cup. Parfait also goes up to K also, but both of those are European Cup sizes, which are way bigger than US cup sizes (ie Europe K cup, is like a US N cup size I think). You will have to do some measuring and look at their size charts to make sure you get the correct fit (for instance, I am a 36/38F in US, but a 36G in Freya and Parfait) They are a little pricey, but I can speak from experience, they are excellent bras, and well worth the money. I have some that are 6 years old that are still in excellent condition. I hand wash mine and hang them to dry. Not sure if they would last as long machine washing.
