The Oversized Button-Up: A Classic Sloper for All Bodies
If there’s one garment that works year-round and across styles, it’s a good button-up. But not just any button-up — one that actually fits the way you want it to. That’s exactly what this Oversized Men’s Button-Up Shirt Pattern delivers.
Whether you’re making it for yourself, for someone else, or adapting it into a custom sloper for multiple looks, this pattern is clean, modern, and designed with real bodies in mind — all sizes, all genders, all styles.
Sloper or Finished Shirt? You Decide
This pattern is meant to give you a versatile base, which means:
You can sew it up as-is for a finished, relaxed-fit shirt.
Or use it as a starting point to develop tailored versions, cropped edits, or even shirt dresses.
Because it’s drafted as a sloper, you’re in full control of the design outcome — no excessive stylistic flourishes unless you add them.
It’s great for:
Wardrobe basics in solid cotton or linen
Statement shirts in bold prints
Layering pieces over tees, tanks, or turtlenecks
Need fabric tips? This pattern is best suited for woven fabric — think cotton poplin, oxford, or lightweight denim.
Gender-Neutral Fit with Sizes XXS–6XL
We’ve had sewists of all genders use this pattern successfully — including for androgynous looks, oversized fits for women, and elevated basics for men. With sizes ranging from XXS to 6XL, you can skip the frustration of traditional sizing charts.
If you’re exploring this for the first time, don’t worry — we’ve got a handy FAQ page that walks you through everything from printing to adjustments.
Not Just for One Project
One thing that sets this pattern apart is how it can be reused for:
Personal wardrobe building
Creating gifts for loved ones
Custom design development (especially if you’re starting your own line)
It’s part of our Menswear Collection, but don’t let that limit your imagination. With a little styling, this shirt works on anyone.
