Both belong in your wardrobe — they don't compete, they cover different jobs. Buy 5–6 white and navy crewneck tees (Sunspel Riviera ~$95, Uniqlo Supima ~$15) for everyday casual and base-layering, plus 2–3 polos in navy and white (Sunspel Riviera Polo ~$160, Uniqlo Dry Pique ~$30) for golf, summer dinners, and any office that calls itself 'business casual.' The two failure modes are: wearing a polo with the collar curling or popped (instant nuke to the outfit), and treating a graphic t-shirt as smart-casual (it isn't, ever). Stick to plain white/navy for both and you've solved 80% of warm-weather dressing.

Frequently Asked Questions
Is a polo shirt business casual?Yes, in most workplaces. A solid-colored polo in piqué cotton with chinos or dress trousers meets business-casual standards in most industries. Avoid polos with large logos, bold stripes, or athletic fabrics in professional settings.
Can you wear a t-shirt to a business casual office?Generally no. A plain t-shirt alone is below business casual. However, a clean t-shirt under a blazer can work in creative industries. When in doubt, swap the t-shirt for a polo or button-down.
Should you tuck in a polo shirt?It depends on the setting. Tucked with dress trousers or chinos looks polished for business casual. Untucked with jeans or shorts is the modern casual standard. Make sure the hem hits mid-fly — too long and it looks sloppy untucked.
What's better for summer, polo or t-shirt?For pure comfort, a lightweight t-shirt. For dressier summer occasions (outdoor dining, vacation, golf), a polo in breathable cotton or linen-blend is more appropriate. Both work — it depends on the setting.
How should a polo shirt fit?Slim through the torso without being tight. Sleeves should hug the mid-bicep without constricting. The collar should lie flat and hold its shape. Length should hit mid-fly when untucked. The shoulder seam should sit right at the shoulder point.
What color t-shirt is most versatile?White. A well-fitting white crewneck t-shirt works alone, under blazers, under open button-downs, and under jackets. Black is second. After those two, charcoal and navy round out the essentials.
