The fabric is great quality. In terms of fit I followed the recommendation to size down from my usual medium and while the shelf bra does accommodate my E cup bust I find the rest of the garment a little tight around the sleeves and stomach for sleeping. I prefer a looser fit, especially over the Mum tum! The shelf bra is only attached at the shoulder line so is a little tricky to get into but once it’s on is ok.
I ordered a size smaller as suggested, still found it too big which is a bit annoying at shelf bra loses its function
