Oasis are currently selling a "New Vintage" line, which consists of a range of dresses in vintage-style floral prints. One of them is this "Lily Lane" dress, which has a sweetheart neckline and slightly flared skirt.

The floral print isn’t too overwhelming, so if you’re not a huge fan of florals you might still be able to wear it, and if you are a huge fan of florals, there’s also a skirt available in the same print.

Get it for £80 at Oasis.
