For our year and a half anniversary I want to give my boyfriend a promise ring. I want to wear a white dress because (to me) it’s serious, like a wedding. Nothing really dramatic though. But I’m looking for a floor length dress that’s kinda simple but also elegant.

I’m a woman with curves so “plus sizes” are mostly what I wear.

I would greatly appreciate some help with this. And I need to keep it around $25 if possible (without shipping)
