Hello! I am going to an event where I will be wearing a halter neck dress, and would love recommendations for a strapless bra of some sort. I feel most I have tried in the past would not stay on or would just offer zero support. I don't tend to wear real bras very often as I wear sports bras at work, but one I have found to be pretty comfortable was size 36G from Wacoal. My only issue with that one is after wearing for a while it tends to dig in a little under my arms.
My measurements are:
Loose Underbust: 36.5
Snug Underbust:35.5
Tight Underbust: 34
Standing Bust: 42
Leaning Bust: 46
Lying Bust: 43.5
The size the calculator recommended was 36FF UK or 36H US
Shape-wise I believe I am fuller on the bottom and the middle, but have a pretty wide root, and also on the more shallow side than projected.
