We need to purchase this ASAP.

If you're looking for something comfy to wear in this sticky, humid heat then Doireann Garrihy's dress is absolutely perfect for you. The Zara number is lightweight but still keeps you covered (and won't be totally sticking to you after walking down to the corner shop). Doireann wore the dress while visiting her newborn niece Hanorah this weekend, and looked fab while taking on some aunty duties. She looks absolutely smitten with the little one in the picture, holding her in one arm as she took a picture with another. She jokingly captioned it: "Two gals feelin’ Saturday night ready. Who’s out?" You can find the Zara number here, and while you're at it, you can also check out the pale pink version, if that's more your style. Doireann has a love for Zara and the colour navy though as she recently wore a similar dress while on a boat trip. The flowing V-neck dress features short sleeves with matching bows and trims in contrasting thread. We absolutely adore it and think it's perfect for a little date night. Dress it down with a pair of white Birks (or the dupe ones from Penneys), or jazz it up a bit with a pair of heels. Either way, it's easy to throw on and there's no doubt that you will look fab.
