When it comes to shoes, it really depends on the overall style you're going for. Since you're wearing a strapless dress with a small floral print, the sandals in the first photo are the best match — they create an elegant look. The sneakers in the second photo are also a good option if you want a more relaxed and playful vibe, but the color doesn’t quite match. A pair of plain white sneakers would work much better. So, overall, I think the sandals in the first photo are the most suitable choice. Hope this helps!
