After watching the scene, you can see how incredible the costumes are and how specifically each character is presented. Costume designer Marilyn Vance (also credited for G.I. Jane, Pretty Woman, Ferris Bueller's Day Off, and The Breakfast Club) did an excellent job incorporating the trends of 1986 into her visions of each character and how they fit into the world on "the other side of the tracks".
Below I've found a few photos - unfortunately I could not figure out how to save the screen shots I took of the film myself on my laptop - that capture the essence of my two favorite characters in the film, Duckie and Iona (Annie Potts, most known as Janine in Ghostbusters).

Duckie
Favorite parts of his costume: the army stripes and pin on his right arm, his western string-tie,
the scarf in his hat band, and his round John Lennon-esque sunglasses
In this scene Duckie is rocking heather grey leather, braided suspenders that clip onto his
shorts. He also is sporting about three pairs of socks and a paisley print Bermuda short.
The color of his yellow sport coat and his red shirt (printed with images of geishas
and samurai) compliment each other so well and are offset by a metallic paisley print vest.
The shoes... need I say more.
Vance's transition from Duckie's day wear to his prom tuxedo is perfection. He wears a navy blue
raw silk tuxedo jacket with the "dressy" version of his string tie, made out of a giant rhinestone.
Iona
Favorites: Her punk rock, porcupine-like hair style and the crazy leather utility belt.
If only I could find a full length picture of this costume. Vance perfectly creates the '80s re-creation
of 1940's fashion (after all, there sometimes is a very thin line). Loving: her pill box hat paired with red fishnet hair net, giant boxy shoulder pads, and the center front key-hole cutout.
The original Lady Gaga.
To me, the yellow slippers and enormous beehive are genius. It shows
that Iona is always true to herself no matter what she's wearing.
