Hey guys
I've been binding with the Underworks 997 for about a year now and whilst it helps a great deal, I have too much going on upstairs to look completely flat.
But I spent some time adjusting my binder last night and it's doing a much better job (hey, all of those enforced sewing lessons in school came in handy after all!).

I've had two problems: my moobs tend to migrate towards each other as the day progresses, so I have to keep pushing them apart to keep them flat; and there's an unsightly bulge at the top of my chest where the compression ends. I've improved these issues by doing the following:
- I found that tightening up the bit that goes under my armpits helps reduce some of the sideways migration issues. I made both sides about 1cm narrower, running down in a vertical strip for about 4cms. This has made my chest much more secure. I then tucked down the top edge of the bits I'd sewn together so that they wouldn't irritate me as I move my arms.
- To improve the bulge at the top of my chest, I shortened the 'sleeves' by about 2cms. This pulls up the chest panel so that it compresses higher up on my chest, and whilst the bulge isn't entirely gone, it looks much more natural.
I know some of you who bind are having similar issues with your binders; I thought you might want to consider giving this a try.
