Currently struggling with size and fit, calculator is recommending 30DD? Does this look right?

[Update] THE 30DD FITS!!!

I was being super silly and not wearing the bra high enough on my ribcage at first lmao but now that that's fixed and I've worn it for a few days I could not be happier! No spillage, no wires digging in, it simply fits! I'm completely shook, this subreddit is amazing, and I hope this post can help someone in the future

Here's the 30DD: https://imgur.com/a/LNk2qeu

Hello all! I've recently been looking for a bra that actually fits after realizing I've worn the wrong sizes my whole life lol. I'm hoping someone could provide some insight with my measurements. I'd describe my breasts as shallow/fuller on the bottom and wide-set/teardrop shape, and I'm currently wearing Natori 32B T-Shirt style.
After measuring myself multiple times with the calculator, these are the 6 measurements I get in inches:

  • Loose underbust: 29.5 // Snug: 29 // Tight: 28 // Standing Bust: 34 // Leaning: 34.5 // Lying: 35
  • Recommends 30DD

And again in centimeters:

  • 74 // 73 // 72 // 86 // 88.5 // 88.5
  • Recommends 30DD

And the recommendations have me absolutely reeling?? Now, I was hesitant to even try a 30C (that was what I got when I measured a few months ago) since my breasts look very small and shallow without a bra, but I recently decided to try that size in a VS balconette (lightly lined and unlined), and it looks like I'm getting a bunch of overflow when wearing them, particularly in the unlined. I'll likely have to return the unlined, unfortunately.

The bands feel great and comfortable on both, snug but not overly tight, and not riding up or down. It's just the cups that seem to be the issue, but I really can't see DD being the correct cup size? Is it just not the right style, maybe? I'd love some recommendations before I spend more money on this :')

Here's some pictures of both bras on me (NSFW): imgur.com/a/5oVYFCO

Thank you for your time and help!!

Edit: I'm going to try both the unlined 30D and 30DD and update with the fit once they arrive. I appreciate all of the quick replies and suggestions, this sub is awesome! Thanks all!
