Preppy Campus Vibes: DIY College Tie Collar Bib for Dogs and Cats (Printable Pattern)

There’s something endlessly charming about a preppy, school-uniform inspired look on a pet — think crisp collars, striped ties, and that timeless Ivy League vibe. But if you’ve ever shopped for college-style pet accessories, you know the drill: limited size runs, generic fabric choices, and price tags that don’t match the quality.

What if you could sew a custom college-style collar bib for your dog or cat at home, in your favorite plaid, solid, or striped fabric, with a perfect fit for every breed from tiny kittens to giant dogs? This printable PDF sewing pattern makes it easy, with a classic campus design, 14 sizes, and a full step-by-step tutorial.

Why This College Collar Pattern Stands Out

This isn’t your average pet bandana pattern. It’s designed to capture that iconic prep school aesthetic, with a structured shirt collar, contrast trim, and a polished tie detail — and it’s built for real-world use:

• Iconic college design: crisp button-down style collar + striped tie detail, instantly recognizable for that back-to-school, Ivy League feel
• 14 sizes from XXS to 9XL: fits teacup kittens, adult cats, small terriers, and extra-large dog breeds — no more “almost fits” frustration
• A4 printable at home: print at 100% scale on standard printer paper, no large-format plotter required. Tape pieces together and you’re ready to cut
• Beginner-friendly tutorial: clear instructions with marked seam allowances, so even new sewists can finish a professional-looking piece in an afternoon
• For dogs AND cats: the structured neckline and adjustable closure work for both feline and canine pets
• Instant digital download: no shipping waits, no customs fees. Start your project the same day you purchase

Supplies You’ll Need

This is a great scrap-busting project — perfect for using up leftover woven fabric from other sewing projects.

• 1/2 yard medium-weight woven fabric (cotton twill, oxford cloth, flannel, or plaid shirting all nail the preppy college look)
• Lightweight fusible interfacing (for crisp collar points and tie structure)
• Hook-and-loop tape (velcro) or snaps for the back closure
• Basic sewing tools: sewing machine, fabric scissors, pins, iron, matching thread
• Standard A4 printer + paper for the pattern

6 Pro Tips for a Perfect Preppy Finish

1. Interface the collar and tie Fusible interfacing is the key to sharp, structured collar points that hold their shape through playtime and walkies.
2. Match stripes carefully If you’re using striped fabric for the tie, take an extra minute to align the stripes symmetrically — it instantly elevates the finished look.
3. Add contrast trim Lean into the school uniform vibe by using a contrasting fabric for the collar lining or tie accent stripes.
4. Topstitch the collar edge A simple line of topstitching along the collar gives a clean, store-bought finish and helps the collar lay flat.
5. Test fit first If your pet is between sizes, cut a quick mockup from cheap muslin before cutting into your nice fabric.
6. Customize it Add a tiny embroidered initial, a small school-themed charm, or mix and match collar and tie fabrics for a one-of-a-kind piece.
