Holly Willoughby's black dress is the kind of piece we need in our wardrobes.

It's a black shirt dress - an absolute must-have for any capsule wardrobe. This particular dress is from Sandro Paris and if you're familiar with the brand you'll know just how gorgeous the pieces are. They straddle the line between high-street and designer and although the pieces aren't cheap, they are well worth the investment. This is the Shirt Dress with Decorative Buttons and it's priced at $395 which works out to about €359. In addition to the stunning button detail, the dress features a belt and we adore the 60s style effect it lends. All in all, it is a truly fabulous piece and although it's pricey, this is something you'll pull out of the wardrobe season after season. The popular TV star has been wearing it with sheer black tights and court shoes but it would also work well with bare legs and sandals, the beauty of it being that you can dress this look up or down. But if you're completely over black and want to introduce some colour into your everyday looks, then Holly also has that box ticked with this M&S dress. Holly's fashion sense isn't for everyone but both of these dresses are wearable items, they can be styled several different ways which is why we're crushing on them so hard. The mum of three shared two floral dresses on the grid but it's the first one that we're completely mad about, the blue is such a pretty shade. Her previous collections with M&S have been a huge success and the latest edit is likely to sell out in record time too.
