What wouldn't go with that? anything from jeans of your cut and style of choice, to a skirt, be it ankle length or only halfway to your knee. It's a very pretty shirt, I expect it would go with most things. Especially a matching white or a black.
Actually, tight, capri cut black jeans, or a knee length white skirt (a more billowy one, not a tight one) would probably look best with it, in my opinion.
Dark Navy jeans.. if you are in the north and you have boots go with those a solid color, if your down south where it is too hot for boots go with a colorful sandal or flats... if you are into jewlery I would go with a small necklace that makes a statement about you.. i. e. i have a thin gold necklace with a dolfin on it.. always a great conversation starter and the guys love that they get to know you through such small details.. next time they see a "dolfin" they will think of you... great trick ;)
hope that was helpfull...
PS hair down and natural... if its natually straight embrace it.. if its curly, treat it well and go all out... guys love a natural look, but well cared natural look...
Lol I dunno why I'm thinking of like a cowgirl style outfit
Maybe like lots of denim and a black leather bag.
Not sure if that's really date-y though... like a skirt or dress is normally good for a date. So maybe try to find something feminine... ooh how about some denim shorts, tuck the shirt into them and wear some girly accessories.
You could wear virtually anything with that top. What are you most comfortable and least self concious in? Jeans, leggings, a skirt, capris? And from there pretty much any color, except I wouldn't wear white.
