If you're in desperate need of a new dress, Showpo offers free express shipping, which means if you live in Sydney you'll get your order delivered within three hours. That's not bad if you're stuck for something unique to wear for the evening as Showpo's collection is very chic at pretty reasonable prices.
Right now you can also get 10% off storewide with their newest promo code, which enables you to choose a dress from the new collection, making sure you're one of the few to have that particular item, reducing the chances to show up dressed identical as some other girl at the party.
From where else could you get a funky maxi dress form the new collection delivered within three hours for just $50? The reason I've picked this Psychedelic maxi in rainbow print is because I like the straps detail on the back, but of course there are several dresses in Showpo's What's New category or you can apply the promo code (see link below) to get 10% off on sales items as well, getting you a dress for as low as $30 if prices dictates your purchase.
