[Measurement Check] Calculator says 32FF/G but usually I wear a 34DD

I used the size calculator and got 32FF/G for UK sizing and 32H/I US sizing.

Loose Underbust: 32 Snug Underbust: 31.5 Tight Underbust: 30.5 Standing Bust: 39.5 Leaning Bust: 42.5 Lying Bust: 39.5

When I was sized at VS they told me 34DDD or 36DD, but their bras were awful. At Soma they measured me and got 34 DD and is the current bra I wear. I'm between grade 1 and grade 2 ptosis from pregnancy/breastfeeding. They are very bottom heavy and my left breast is almost a cup size larger than my right. I just feel like my current bra is uncomfortable and ill fitting. My left breast spills into the middle, but still has a gap on the side. The right breast seems to fit the cup fine, but I think the band is too loose. If I tighten the straps more for lift, the band lifts up and my breasts fall out of the bottom.

I guess I'm really looking for a measurement check and recommendations for a wireless and not wireless bra for my shape and size. I really want something comfortable and supportive for everyday use as well as one that can perk the girls up a little for lower cut shirts.
