When Sue Blane attended the Orlando 2001 convention, Tom Finch, an excellent Dr. Scott, took the time to talk with her about Dr. Scott's costume. I had planned originally to print this in fanzine "Crazed Imaginations."
I misplaced the article, and this seems like the logical place for it.
What would have been Tom Finch's article is reprinted here. Thank you so much, Tom!

Pre-Dinner Scene:

• 3-button gray jacket, light blue dress shirt buttoned all the way up, brown mustache, horizontally-elongated octagonal gold wire-rim glasses.
  The glasses can be found at a frames shop if you look around long enough. They have been spotted at Lenscrafters, and may be available either through Armani or Polo Ralph Lauren. One Dr. Scott even found a pair in the reading glasses section at Walgreens!
  The jacket has a subtle white striped design. Only the top button is buttoned. Buttonhole in lower left lapel. 3 button cuffs with dark buttons.
• Maroon tie with diagonal stripes.
  Stripes angle from Scott's upper left to his lower right. For whatever reason, most ties in the UK (and Australia) have the stripes angled backwards from most US ties. So if you live in the US, paint or sew the stripes on your tie. Or try eBay's UK or Australian sites - my husband did a 10 minute search and found some really nice ties. One dedicated Dr. Scott, Scott Labrecque, even had a custom tie made. (If you do, make SURE they get the colors right! He had to have it done twice.)
  Stripes:
  
  A gray stripe is visible on the top of the knot.
  Just below knot: thin white, maroon, orange.
  Just below collar tips: thin white, thin maroon, wide gray stripe.
  Mid-chest: white, maroon, red/orange, maroon, thin orange, thin maroon, wide gray. Rectangular metallic tie clip below the wide gray stripe that extends halfway across the tie.
  Above the navel: white, maroon, orange/red.
• Pens and pencils in pocket.
  Number changes from scene to scene. Pencils are points up; several pens are clipped to the pocket.
• Round black magnifying glass, marijuana cigarette
• Light brown teddy bear with red bow around neck, black plastic nose, and black button eyes. Arms and legs are separately stuffed pieces.
• Long ballpoint pen
• Round black cufflinks
• Watch on right wrist
• Eddie note (lipstick or marker on plain white paper; crumple). Kept in inner right hand pocket.
• Plaid blanket (blue, red, yellow, black and white). Covers his lap and legs so only his slippers and socks show. The tartan appears to be Anderson Modern (thanks to Scott Labrecque for digging this up). You can order wool blankets through tartan companies such as Scottish Lion; see our Links page for suggestions.
• Rust-colored smooth leather men's slippers (leather sole). Maroon socks.
• Wheelchair This is the classic Everest & Jennings foldable style, with brown padded armrests. metal spoked wheels and front casters, bicycle handle style push handles, and separate metal footplates. The handrim on the back wheels is also metal.
  They're getting harder to find as wheelchairs modernize.

Floorshow:

Take your coat off and drape it over your shoulders. Remove slippers and socks.

• Black undies, seamed fishnet stockings, black garter belt with crinkly metallic red straps, black high heeled pumps.
  The fishnets have just a few sequins on them.

You could wear all this under your plaid blanket from your first entrance.
