But by the looks of these pictures, it wasn't long before poor old Pro was getting a wee bit bored with all the shopping.
Former Made In Chelsea star Millie shared a snap of her first picture, and said: "New sunnies selfie.. @professorgreen looks suitably uninterested!"
And as she happily flicked through the rails of potential clothes, Millie added comments like: "Zara keeps getting better this season!"
Pro, however, was tiring with all the shopping.
He shared a snap of himself raising his eyebrows and looking tired, as he said: "She's been shoe shopping for a while now."
We reckon Millie, who married her rapper hubby last September, learned a valuable lesson after her Sunday (13 April) shopping spree...
