"Peek-a-boo" or "cut out" dresses will be very popular this spring and I think every girl should have a flirty variation of one in their closet! It's a clever way to show a pinch of skin and a great departure from the conventional "here's a ton of cleavage" route.
If you're the daring type, try rocking a dress with a large panel out of the back or sides. For the more modest something like this coral River Island dress shows just the barest hint of skin and is subtle, but still scandalous. These dresses come in a ton of variations so there's really a version for anyone!
I'd personally avoid jewelry that's too gaudy or shimmery when accessorizing this look. Instead, exude charm and simple sexiness by rocking dangle earrings or a fun ring!
