When Busy Philipps' daughter Birdie needed a dress to wear to the Olivia Rodrigo concert at Madison Square Garden, she dove into her famous mom's closet.

The 15-year-old wore a vintage Betsey Johnson dress that Philipps, 44, first wore to the premiere of The Green Mile in 1999 with then-boyfriend Colin Hanks, 46.

The burgundy, crushed velvet midi-length frock featured black lace trim at the bodice and straps.

When the Freaks And Geeks star wore it 25 years ago, she paired it with the deep maroon lipstick shade that was popular at the time.

Birdie put her own spin on the 90s look by accessorizing with a delicate heart necklace and opting for minimal makeup.

Philipps shared a side-by-side of her in the dress and her daughter in the dress to Instagram on Thursday.

'We love Olivia Rodrigo so much. it was beyond special to get to see her at MSG last night,' Busy's caption began.

'Such an incredible rock show! I feel so lucky I get to be the mom of these kids. 

'Someday I WILL find the picture of a 12 year old @oliviarodrigo with a 6 year old Birdie Silverstein at a meet and greet for Grace Stirs Up Success,' she continued.

'Also- please enjoy the side by side of me at age 19 and birdie last night in the same dress- YES ITS TRUE WE LOOK V SIMILAR ( dress is @betseyjohnson from the 90s!).'

The Betsey Johnson Instagram account shared the side-by-side photo and captioned it: '#Twinning alert! Birdie wore the same vintage Betsey dress that Busy wore in 1999 to the GUTS tour. #VintageBetseyJohnson #BetseyBabes.'

The Girls5Eva star commented on the legendary designer's post, writing: '2 @betseyjohnson girls 4 life!.'

Busy shares Birdie and Cricket Pearl, with her ex-husband Marc Silverstein. The exes still live together so they can share parenting duties.

Busy sent Birdie to boarding school in Sweden last fall and revealed how hard it was to see her leave.

'Birdie's such a strong individual,' she added of the teen who she has previously stated presents as 'femme-presenting non-binary' with a preference for they/them pronouns.

'She's such a smart, unique person that I feel really confident in her ability to succeed in whatever situation she's in,' she added.

She explained that she knew her daughter wouldn't stay at boarding school if she felt like it wasn't a good fit. 

'If it turns out this is not the situation for her, and I'm not saying that will be the case, so be it,' she matter of factly said.
