The €55 River Island dress that would be FAB for a wedding guest outfit.

It's the Black Spot Maxi Slip Dress and we just love everything about it - the tie detail, the open back, the floor-length and it looks much more expensive than its affordable price tag. Such a dressy piece, it would be ideal for a special occasion and would also make the perfect wedding guest outfit. Another advantage to this €55 River Island dress is the fact it's so easy to style, simply pop this on with barely-there sandals and a statement clutch for an elegant, stylish look. The polka dot pattern continues to be a massive trend and this is a subtle take on the look. It also comes in a red and pink checked pattern but we're all about the monochrome choice. Just look at how fab this €55 River Island dress from the back, it really reminds us of a designer piece. We also have our eyes on another River Island buy, the Black Print Midi Slip Dress and the bright colours are just ideal for this time of year. This would look fab with a blazer and a pair of barely-there sandals for a wedding or special occasion. You can then make sure you're getting value for money by wearing it again casually, adding white trainers or sandals and a denim jacket. This second dress is priced at €50 which isn't the cheapest summer dress we've come across but the detail is fab including the ruffled neckline, tie detail and side slit. As you'll see from these outfit picks, printed and patterned pieces continue to be a huge trend and if you haven't yet purchased a polka-dot dress for your own wardrobe, now is most definitely the time. Hurry up before both of these dresses sell out!
