Fit check - 38F Cleo Juna Balconnet

This is the first of a few bras I have or will be ordering from Amazon.
Here are my measurements (in inches and cm):

Loose underbust: 38in (96 cm)
Snug Underbust: 35in (90 cm)
Tight Underbust: 34in (87 cm)
Standing bust: 43in (110 cm)
Leaning bust: 44in (113 cm)
Lying bust: 46in (116 cm)
The calculator recommended size was 38E/F

I feel like this bra fit 'ok' but I don't really know what that means yet. I almost think this is cakes on a plate. But maybe not! I have no idea what I'm doing! But I'm giving it a shot...

• Based on these pics, did I get it into my IMF the right way? Is the gore in the right place? Too high/low? Are the straps supposed to be this wide? This pic doesn't show the gaping on the right side. Which leads me to...
• I know my right breast is smaller than my left one, so I guess that explains the gaping, but is that just something I will have to live with, or do I need a different size?
• Do the wires look like they are in the right place?
• And what about the back? (oops...time to clean my mirror, I guess lol) My back fat is kind of protruding from it, and it seems very tight around.
  I tried it on upside down and backwards and it seemed to fit just fine.

I have a Cleo Marcie coming next week so will post a follow up. If anyone has any other recommendations, I'd love to hear them.

EDIT: after wearing the bra about 45 minutes, my arms started to get pins and needles. I think I need something else!
