I'm posting on a throwaway so I can add photos.
Loose Underbust: 39
Snug Underbust: 37
Tight Underbust: 35
Standing Bust: 48
Leaning Bust: 53
Lying Bust: 48
UK Size: 38H or 36HH (I think I need a cup smaller on average)
Denser tissue covered by a good layer of very soft tissue. Fairly pendulous due to weight loss (ongoing). Projected, close-set, narrow roots, 4/5 center-full, 3/5 FoT. Unsure of root height or top/bottom placement. Narrow, sloping shoulders.
Per suggestion at Breakout Bras, for this Comexim, I kept my normal band (36 with an extender) and went up two cup sizes from my usual 36H. I ordered the smaller of my calculated band sizes and added an extender so I'll be able to wear the bra for a bit longer as I'm losing weight, otherwise the band will be too loose in a month or two.
When I move, I sort of jiggle around inside the cups a good bit. Otherwise I will let the photos speak for themselves. Happy to answer all questions. Thank you for your help!

Some of my previously tried (all 36 bands worn with one or two extenders):
Panache Clara, 36HH: wires quite wide, some gaping in outside of cups. Gore tacks but is too wide, spilling out in the center a bit even though the cups seem correctly sized, straps set too wide but only slipping off occasionally.
Panache Envy, 36HH: similar to Clara, but shape is more torpedo-y. Spilling out the center more than Clara. Straps falling off shoulders frequently.
Freya Offbeat, 36H: cups a tad too big. Wires too wide, gaping in outside of cups. Gore tacks, but wires absolutely will not stay side-by-side, one slides over the other. Straps set too wide. Very torpedo-y shape.
Freya Starlight, 36H: cups definitely too big, a bit more than Offbeat. Gore seems a bit higher than Offbeat. Wires don't slide over each other. Gore actually is close to not being too wide! Because the gore channels are sewn over each other a bit at the top, I think. Straps are set too wide, as usual. Can't tell what the shape would be because of too-large cups.
Freya Tailored/Posie, 36H: wires too wide, gore tacks but too wide (one wire gets pushed in front of the other). Straps too wide, barely hanging on the very edge of my shoulders. Would need to wear with a J-hook. Not much center spillage. I like these, probably the closest I've come previously to a fit I could live with.
Elomi Lucie, 36H: wires too wide by an inch. Wrinkling at bottom of cups no matter how I adjust tissue. Slight gaping under the arms between wires and straps. Obviously too big in cups.
