I ordered, and then doubting my decision, reordered this very dress, pre sale, wanting to love it. Size 10, size 8. But it was terrible. Swamped me. Also: Strangely garish in real life as pp said. And if I recall rightly (equally garish) gold buttons at the top, which further ruined the look.
But I don’t think the style is old fashioned. Then again, I’m in my 50s, and these days I’m usually looking for “effortless chic” rather than high fash cool. Think you’ve done the right thing returning it.
