Wedding dress with inlaws

Leatrice

My mother in law and my fiance's sister in law told me I looked like an old lady, I paid to much, I should've taken them because I rushed into it, and I should've got something tighter like a mermaid dress. I cried and my fiance was in tears when I tried it on. I don't like tight and am very self conscious. We only paid 1300 for it. And I only wanted my fiance there because I didn't want to feel judged due to my social anxiety. Trying on dresses was hard enough for me. Did I make a mistake?

Please keep in mind that I had a baby 2 months ago when you look at this picture.
