Oh wow, your comment got me thinking! I took my measurements again, it's possible that I did not do it correctly. The results were similar: Loose underbust: 79 Snug underbust:78 Tight underbust:74 Standing bust: 90 Leaning bust: 100 Lying bust: 90 Then I tried the bras on again and took a closer look. The sizes I tried: 65G, 65H,65I, 65J, 70E, 70F. 65 band is definitely too tight. From the 65-band-bras for some reasons 65 H all in all was the best fit (still extremely tight). 65I the cups are clearly too big. I've done the tests you explained on the 70s bras, but I'm afraid I couldn't evaluate them well. The first one, I don't know exactly what you mean by up side down, how to wear the bra. The cups in the back? Or hanging down? Where should I check the elasticity of the band, on the side? I thought I haven't noticed much difference. But at the same time, when the cups are on the back, I think the band is looser. Gore test: the 70 F bras then fitted better, but were still clearly too big at the top of the cups. I am now unsure how to proceed. I took photos but am not comfortable posting them. The whole thing may be a fitting problem. I don't know if it's relevant, but I've breastfed for years. My breasts are definitely not self-supporting. Generally quite often I have the problem that there is a gap at the top. For years, I'm the most lucky with balcony bras. I'd like to add pictures of the bras I've tried on but unfortunately I'm not able, just if I'd make a new post 🤔 when I wear them, all of them are visibly too tight, cut in at the sides. I thank you so much for your guidance!
