How to DIY Lucas' Iconic Look


Lucas's signature look is all about 80s-inspired practicality with a touch of youthful energy. Get ready to transform yourself into this resourceful adventurer! If you're looking for ready-to-wear pieces, we've got a shopping list for you above. Want a budget-friendly or customized approach? Let's dive into DIY solutions that will make your Lucas costume stand out.

Classic Striped Tank Top

  • What You Need:

    • Plain tank top (preferably with wider straps)
    • Fabric paint in various colors (red, blue, green, yellow, etc.)
    • Painter's tape
    • Cardboard or thick paper
    • Paintbrush
  • How to Do It:

    1. Prep Your Surface: Slide the cardboard inside the tank top to prevent paint from bleeding through.
    2. Create Stripes: Use painter's tape to mark off horizontal stripes of varying widths across the front of the shirt. Experiment to recreate Lucas's stripe pattern.
    3. Get Painting: Carefully fill in between the tape lines with your chosen colors. Allow each color to dry before applying the next.
    4. Finishing Touches: Once completely dry, remove the tape. For added authenticity, consider lightly distressing the edges of the tank top with sandpaper.
  • Bonus Tips:

    • I've found that fabric paint in primary colors gives the best '80s vibe.
    • If hand-painting is tricky, try using fabric markers for more control.
    • Look for tank tops at thrift stores for an even more budget-friendly option.

Versatile Khaki Shorts

  • What You Need:

    • Pair of khaki-colored shorts (chino style is ideal)
    • Brown fabric dye (optional)
    • Scissors
    • Sandpaper
  • How to Do It:

    1. Find the Fit: If you can't find the perfect shade of khaki, start with a lighter pair of shorts and use fabric dye to achieve Lucas's color. Follow the dye instructions carefully.
    2. Adjust the Length: In the show, Lucas's shorts fall just above the knee. If your shorts are too long, carefully trim the hem and create a slightly frayed edge.
    3. Weather the Look: To give your shorts that well-worn feel, lightly rub sandpaper along the edges and pockets to create subtle distressing.
  • Bonus Tips:

    • Look in the boys' section of clothing stores to find shorts with a more authentic '80s fit.
    • Lucas's shorts have an elastic waistband – check the athleisure section if you're starting from scratch!

Iconic Bucket Hat

  • What You Need:

    • Plain, light-colored bucket hat (canvas or cotton works best)
    • Fabric scraps or an old t-shirt in a similar color
    • Scissors
    • Needle and thread (or fabric glue)
  • How to Do It:

    1. Measure and Cut: Cut a strip of fabric long enough to wrap around the base of the hat with some overlap. The width of the strip should be about double the desired width of the band.
    2. Fold and Attach: Fold the fabric strip in half lengthwise and either sew it around the hat's base or use fabric glue for a no-sew option.
  • Bonus Tips:

    • This is a great way to use up leftover fabric – the band doesn't need to perfectly match the hat!
    • For extra sturdiness, iron on some fusible interfacing to the fabric strip before attaching it.

Adventure-Ready Canteen

  • What You Need:

    • Plastic or metal canteen with a canvas cover
    • Brown fabric dye
    • Brown leather or faux leather cord
    • Scissors
  • How to Do It:

    1. Customize the Cover: If your canteen cover isn't the right shade of brown, use fabric dye to transform it.
    2. Create the Belt Loop: Cut a length of leather cord long enough to wrap around your belt with extra to tie the canteen securely. Attach the cord to the back of the canteen cover using sturdy stitches or fabric glue.
  • Bonus Tips:

    • Search for vintage canteens at thrift stores or army surplus stores for the most authentic look.
    • I think a canteen is one of the coolest parts of Lucas's outfit – play up its usefulness!

With these DIY tips, you've nailed the core elements of Lucas's practical style. Now, let's shift gears and explore how to capture his determined personality and signature mannerisms!

  • How To Do It:

    • Start with a neutral expression.
    • Slowly roll your eyes upwards while slightly tilting your head back.
