I had cups sewn in and it was the BEST decision EVER! I have a good strapless bra from VS, but I didn't want to be fussing with a bra AT ALL during the day (especially in the heat), so I had the cups sewn in, and they made the girls look better than they do in the strapless AND it was so much more comfy!! I'd definately recommend the cups if it's an option.
