Nearly 300 of the actor’s items, from designer gowns to everyday basics, to be sold in Los Angeles, with some lots under $100

A customised sunhat. A slogan sweatshirt. A “mom” necklace. An old copy of Cosmopolitan. If these sound like items found in many homes today, they’re actually the castoffs of a household name: Gwyneth Paltrow.

Next week, nearly 300 pieces owned by Paltrow will be on sale as part of an auction at Julien’s, the Los Angeles auction house that has sold big-ticket items such as Marilyn Monroe’s so-called “naked” dress and the leather jacket worn by Olivia Newton-John in Grease. But, while those items went for six-figure prices, Paltrow’s sale is a little more affordable, with estimates starting at about $50 (£37) to $75 (£56) for some of Paltrow’s personalised stationery.

At the time of writing, a Dolce & Gabbana 2001 T-shirt with the slogan “Material Girl” has attracted 16 bids, including one of $800 (£598). A RED Valentino jumpsuit is already at $600 (£449). And someone has put a $700 (£523) bid on Paltrow’s “mom” necklace. A Goop black jumpsuit is currently only on $50, however. And two photos of her ex-husband Chris Martin and his band Coldplay have had a bid of $100. More bids are expected in the run-up to the auction on Tuesday.
