“Real Housewives of Beverly Hills” star Sutton Stracke will donate clothes from her own closet to a Central Park thrift store.

The effort, which launches this week, is part of a month-long “circular fashion event” to promote second-hand shopping instead of off-the-rack.

Customers of Central Park Resale Consignment on West 66th Street will find discounts on luxury brands like Dior and Dolce & Gabbana. 

A portion of the store’s profits over the month will be donated to the National Alliance on Mental Illness. The organization is close to Stracke’s heart, as this month brings the 20th anniversary of her father committing suicide, Central Park Resale owner and a lifelong friend of Stracke’s, Tanya Williams, told The Post.

Sutton is expected to appear at a kick-off event at the store on Dec. 16.
