I noticed that a handful of people report this as being too small, too large, or just right. This makes me think that it is just not made in a consistent manner. I am a US 36i or a UK 36g. I couldn't find the info to see if their sizing is US or UK, which I may have just missed, but I decided to go ahead and try the 36g. It was too small in the band, I couldn't even buckle it, but the strange part is that the cups fit perfectly. I noticed that the tag says US 36g AND UK 36g, which is most definitely not the same. Maybe it's mismarked? Even though the sizing was off, I think it's very well made, supportive, and comfortable. I'm 5'10" so I have a longer torso than most, but it ended just below my ribs, and didn't dig in. I like it enough that I'm going to try the next band size up and reevaluate my review. However, I do feel that if something costs this much, it should be produced with consistent sizing and be marked appropriately.
