If you're one of Instagram's five million monthly active Australian users, you'll be well aware of the immense pulling power of the social media app when it comes to style and shopping. After all, when following your favourite celeb or blogger, style stalking their latest shoe, bag or outfit is part of the reason you follow them in the first place - right?

The same goes for your favourite retailer - Instagram is easily to most up-to-date way of learning which products have dropped in store that day. And now, thanks to luxury European e-tailer mytheresa.com, shopping just got even simpler with news that you can buy direct from your Instagram app. While it's great news for your instant gratification and bad news for your credit card, the @mytheresaprgirl Instagram feed cuts out the usual web searching by allowing you to shop from within the app (anything to save time!). Any image posted on from @mytheresaprgirl that has the hashtag #buytheresa is available to buy direct at instashop-mytheresa.com (the URL in the feed's bio). Pretty nifty, huh?
