Good shirt
Size: Small, Color: Black
Very nice shirt, I usually wear medium but I had to get one size smaller. The small men size fits my collar great but the dryer might shrink it.

It’s not Polo but a good shirt
Size: X-Large, Color: White
I too thought it was Ralph Lauren Polo but found out that it was US Polo Association. It is a bit boxy but fits well. It is a good quality shirt and a good value for the price. Runs true to size.

Cute and stylish
Size: Large, Color: Aqua Light
Got this classic polo for my husband and he’s genuinely impressed. The fit is clean without being too tight, and the fabric feels soft but still holds its shape after washing, which is a big win. It has that polished, casual look that works for both everyday wear and slightly dressier occasions.
He also mentioned it’s really comfortable, not stiff or scratchy like some polos can be. Overall, great quality for the price and definitely something he’ll keep reaching for.

Great everyday polo
Size: XX-Large, Color: White
I picked up the U.S. Polo Assn. Men’s Classic Two-Button Pique Polo as a casual summer and golf shirt and ended up wearing it far more than I expected. The fit is true to size with a comfortable classic cut that isn’t too slim or baggy, and the lightweight pique cotton feels breathable and perfect for warm weather, whether you’re on the course or just running errands. For the price, the quality really surprised me—the fabric feels durable yet soft, the collar keeps its shape after washing, and the stitching looks solid without feeling cheap. The style is simple and versatile, easy to pair with jeans, shorts, or chinos, and the logo is noticeable but not over the top. After several washes there’s been no major shrinking or fading, especially when washed cold and air dried. Overall, this is an affordable, comfortable, and reliable polo that looks good and holds up well, and I’ll definitely be buying more colors.
