Posting a gallery of herself wearing high-waisted white Isabel Marant pants and holding her favourite Bottega Veneta pouch bag, Rosie's followers were quick to ask where her basic everyday top was from. On one person's comment, the mother-of-one replied, "Zara 🎈"
Looking back at her grid, it appears that last week, Rosie posted a photo wearing the same design in black, paired with a pleated white Chloe skirt.
While the bodysuits unfortunately aren't available to shop yet on the Zara Australia site, they retail for just $19.95 USD (approx $29.4 AUD).
We don't know about you, but we'll be keeping a very close eye on Zara's new arrivals over the next few weeks.
