I have some 34D Fiona models over two years old that are obviously great quality, but desperately need to retire. Thinking I would improve on a good thing, I ordered the Helena. Unfortunately for more money I got a worse fit. Although fit is unique to each, I cannot recommend this bra based on craftsmanship, either. The nylon material of the Helena is both slicker and thinner, but less breathable so sweat and air do not pass. The support was excellent, but for those of us interested in high-impact, not quite as good as the best maximum motion control bras. The M-frame itself was unnecessarily stiff (support should come from the band), and bent in the awkward places... it only slightly hindered encapsulation but greatly annoyed me. The stretch in the cloth was comfortable, a little lax but nothing troublesome, and in fact I would probably even still have kept the bra had the underarm bite not been intolerable. Generally I do not have problems in that area. It irritated my armpit and underarm in just a few minutes for hours later, and I did not even exercise once in it. Since I have no use for clothing I cannot wear, I will be ordering more of the Fiona, and have already returned the Helena.
