Getting stressed about disappointing my fiancé

hi everyone! So I’m in the phase of planning looking at the wedding dress and I just had a pretty…disappointing conversation with my fiancé. He was talking about how he’s always wanted to see me in something sleeveless and form-fitting that would show off my assets and exude confidence. That is…not what I envisioned to say the least. I’m more so looking for something with a slouchy strap to hide my arm fat that I don’t like and something maybe a-line that will hide the little things like my stomach. I’ve never seen myself in anything sleeveless or form fitting (I’m short and my single thigh is the size of the average dress model’s waist lol). I can’t help feeling now like even if I buy something I love, he’s going to have some lingering disappointment…
