RSQ Button Up Shirt – Classic Fit & Modern Style
Our RSQ button up brings clean lines and comfortable wear to your everyday rotation. Crafted from a durable cotton-poly blend, this shirt resists wrinkles and holds its shape wash after wash. The relaxed fit through the shoulders and chest gives you freedom of movement without feeling boxy.
We designed the button-up collar to lay flat whether worn open or buttoned, and the button placket uses reinforced stitching at every closure point. The tailored hem works tucked in or left out, making this piece equally at home in the office or on the weekend. Available in solid neutrals and seasonal prints, the RSQ button up adapts to your personal style.

- Button-down collar with reinforced placket stitching
- Machine washable – tumble dry low

Fabric & Construction Details
We blend 60% cotton with 40% polyester to give you the breathability of natural fiber and the durability of synthetic. This combination resists shrinking and keeps the shirt looking crisp through repeated washing. The fabric weight sits at a medium 5.2 oz per square yard, substantial enough to drape well without clinging.
Every buttonhole is double-stitched and bartacked at stress points. The seven-button front placket uses durable corozo buttons that won’t crack or fade. Side seams are double-needle stitched, and the armhole reinforcement prevents separation even after extended wear. We finish the collar with fused interlining so it maintains structure without feeling stiff.
Sizing & Fit Guide
How the RSQ Button Up Fits
Our relaxed fit gives you 2-3 inches of ease through the chest compared to your measured size. The shoulder seam sits just past your natural shoulder point for a comfortable drape. Sleeve length is cut for a standard arm, ending at the wrist bone when arms are at your sides.
The shirt measures 29 inches from high point shoulder to hem in size medium, providing coverage whether tucked or worn loose. Chest width across the front panel measures 22 inches laid flat in medium. We recommend ordering your usual size for the intended relaxed fit, or sizing down one if you prefer a closer cut. Refer to our full size chart for detailed measurements across all sizes S through XXL.
Care & Maintenance
Machine wash cold with like colors using a standard detergent. The cotton-poly blend releases stains more easily than 100% cotton, and the fabric maintains its color vibrancy through repeated washing. Tumble dry on low heat or hang to dry – both methods work without significant shrinkage.
If wrinkles appear, a quick steam or warm iron on the cotton setting smooths the fabric. We build wrinkle resistance into the weave, so most customers find the rsq button up needs minimal touch-up straight from the dryer. Avoid bleach and fabric softener, which can break down the fiber blend over time. For long-term storage, hang on a sturdy hanger to preserve the shoulder shape.

RSQ Button Up Shirt Questions
Our button up has a relaxed fit with more room through the chest and shoulders than a typical dress shirt. It’s designed to be worn comfortably untucked, so the hem is shorter and the side seams are cut to drape naturally when not tucked in. If you normally wear a medium in fitted dress shirts, stick with medium here for the intended relaxed look, or size down to small for a closer fit.
Yes, especially in our solid colorways. The clean lines and button-down collar give it a polished appearance appropriate for business casual settings. Many customers wear it to the office paired with chinos or dress pants. The wrinkle-resistant fabric keeps you looking sharp throughout the day without requiring touch-ups.
The button up uses a lighter cotton-poly blend that works year-round and requires less maintenance. Our <a href=’//mens-tops/;-/rsq-flannel/;-/rsq-shirt//’>flannel styles</a> feature heavier brushed cotton in traditional plaid patterns, designed specifically for cooler weather and layering. The flannel has a softer hand feel, while the button up offers a crisper, more structured appearance.
Yes. The cotton-polyester blend resists shrinking when tumble dried on low heat. We’ve tested the fabric through 50+ wash cycles and measured less than 1% shrinkage. For best results, remove the shirt promptly from the dryer to minimize wrinkles. Hanging to air dry also works well if you prefer that method.
It runs true to size for a relaxed fit. Check the chest measurement in our size chart and compare it to a shirt you already own that fits well. The shoulders are cut generously, so if you’re between sizes and prefer a slimmer look, we recommend sizing down. Most customers find their usual size works perfectly for the intended casual-to-smart-casual style.
Seven buttons run down the front placket from collar to hem. Each button is securely attached with reinforced stitching and bartacking at stress points. The buttonholes are double-stitched to prevent fraying, and the corozo buttons are durable enough to withstand frequent washing without cracking or losing color.
Our core collection includes charcoal, navy, stone, and white solids that stay in stock year-round. We rotate seasonal prints every few months – recent options have included subtle geometrics, micro-checks, and tonal stripes. Color availability varies by size, so check the product page for current options. New prints typically launch at the start of each season.
