The slip dress layered under a trench coat and the feather-trimmed fringe mini both deserve attention alongside the more famous rainbow-striped look.
1. Rainbow Dress
This is the rainbow-striped dress Jenna Rink wears to the magazine party, and it remains one of the most recognizable looks from any rom-com of the past two decades.
The multicolored horizontal stripes run across a fitted bodice and flared skirt, hitting just above the knee.
You can find close matches at a range of price points. Look for a dress with saturated jewel tones rather than pastel stripes; the contrast between colors is what makes the dress read as bold rather than whimsical.
The fit matters more than you might expect. A too-loose bodice will lose the polished silhouette that made the original work, and a skirt that doesn’t flare will feel more like a casual sundress than a party piece.
Pair it with simple shoes and let the dress do all the work.
2. Slip Dress with Trench Coat
A satin slip dress layered under a structured coat gives you the polish of a full outfit with the ease of 2 pieces you likely already own.
The slip here is a deep plum or navy with delicate lace trim at the neckline, and the cream coat adds weight without covering the dress entirely.
Temperature decides where this works: spring or fall when you actually need the layer, not as a styling trick in July. Choose a slip dress that sits a few inches below the coat hem so the proportions stay balanced.
Sunglasses and a bold heel finish the look, but the real lift comes from the texture contrast between the matte coat and the glossy slip fabric.
3. Fringe and Feather Party Dress
Tiered fringe and a feather hem turn a simple mini dress into something that moves with you, and the sequined fabric catches light from every angle.
The pink tone here is soft rather than neon, which keeps the dress from tipping into costume territory.
Fringe dresses run short by design, so this works best if you’re comfortable in a hemline that sits mid-thigh or higher. The feather trim at the bottom balances the fitted bodice but locks you into dry cleaning.
Oversized fluffy earrings echo the texture of the feathers without competing for attention.
Popularity of the Dress
The costumes she gets exactly right have reminded viewers why they loved Jenna Rink’s wardrobe in the first place.
That visibility has pushed the rainbow dress back into costume rotation. I expect to see more Jenna Rinks this Halloween than in any year since the movie came out, and the dress is no longer a niche reference.
It sits somewhere between instantly recognizable and still specific enough to feel like a choice rather than a default.
The TikTok resurgence has also made it easier to find ready-made versions of the dress. Retailers stock it now in a way they didn’t before the recent resurgence.
The specific search phrase “13 Going on 30 dress” has been steadily rising for the past year, beginning in early November 2020 and spiking in July 2021 and again this month.

Fashion Trends
Early 2000s fashion has come back in a way that makes the costumes from this movie feel current rather than nostalgic.
Slip dresses, satin finishes, and brightly colored party pieces all fit into what is already in stores, which means you can wear these looks outside of a Halloween context and still read as on trend.
The timing matters.
A look that felt dated a decade ago now feels like part of a broader return to Y2K silhouettes, and the rainbow dress benefits from that shift. It no longer requires explanation or irony to work in an outfit.
If you already lean toward early 2000s shapes, these pieces slide into your wardrobe without friction. If not, they still work as standalone statement pieces that don’t require you to dress around them.
