5 Under £50: Royal Garden Party dresses from Next

Next month, the boyfriend and I will be attending a garden party at Buckingham Palace. It is, without doubt, a once in a lifetime opportunity and one which, obviously, requires a dress to live up to the occasion. Of course, being a bargain hunter, I have set myself a budget of £50 to find a dress. I will wear a pair of shoes from my over-flowing shoe rack and a hat or fascinator will be extra - or borrowed! So over the next week or so I will be "visiting" a few of my favourite online stores and picking my top five picks under £50. Today's are from Next:

Clockwise from top left: Linen blend shift dress; Spot print shirt dress; Linen blend shift dress; Crossover mesh dress; and Black and white tweed effect shift dress.

Help me to choose which dress I should choose for the Royal Garden Party?
