Rosey Posey Creations make bespoke head-wear that is perfect for weddings, christenings, music festivals, holidays and proms. They have a wide selection of floral crowns, headbands, combs and hats which can be used to make an outfit look and feel more summery! Above are some of my favorites, although it was hard to choose as they are all so lovely.
You can check out their website here or take a look at their facebook and twitter pages.
