I don't think I've ever worn an underwired bra in my life! I usually buy non-wired bras from M&S or Tesco, but just this last week have bought some pull-on bralette type things, rather like yours, which are incredibly comfortable, although not desperately supportive (now I no longer skate, that doesn't matter - when you are jumping, you need support or it hurts!). Incidentally, should you tire of making your own, or need a bra for a special occasion, the place to go is John Lewis, who I've always found have been incredibly helpful, and you can specify that you won't wear an underwire, and they respect that.
