Katie Holmes spends $25,000 a month on her daughter's clothes.

The 'Mad Money' actress is reportedly determined for three-year-old Suri - her child with husband Tom Cruise - to be the "most fashionable kid in Hollywood" and her recent purchases for the youngster have included a $5,000 ruby pendant and two dresses priced at $1500 each.

A source told Britain's Grazia magazine: "Dressing Suri in amazing outfits has become Katie's favourite hobby. She'll scour the internet and Beverly Hills shops to find items and get inspiration for different looks.

"One of Katie's favourite looks is 80s-inspired - she puts Suri in leggings and long sweatshirts or bright dresses. Suri loves getting involved and choosing things too."

Katie caused controversy recently when pictures were published of the star and Suri, with the youngster wearing a pair of high-heeled shoes, and the insider admitted that the tot had problems walking in them.

The source added: "Suri can't always walk in her heels, sometimes she just steps right out of them."
