"Topshop's PERFECT lil summer dresses are everything today... Fancy an ice cream?" Flack captioned the snap, showing off her new striped sundress.
To save you valuable browsing time, we've found Flack's "perfect" dress on the Topshop website.
It's the Stripe Wrap Slip Dress and it will set you back £39.00 (it's also still available in every size, at the time of writing, so act fast).
Fans of the summery style will also be pleased to know there's a whole host of equally stylish wrap dresses on the Topshop website.
Now all we need is the sun to come out again.
