Very nice shirt, runs a little big depending on how you like it to fit
Color: 311 Black, Size: Medium
We got it specifically for the black and white stripes. My husband typically wears a medium. We buy the WYR shirts for him since they have a tapered, flattering fit. I initially ordered the medium but it was too big and baggy especially in the waist. We ended up getting the small and it fits perfect. I really like the hand of the fabric.

Seems great so far - 3 washes and nothing but good things to say
Color: 311 White, Size: Large
Shirt looks great colors wise and it's lasted perfectly so far in limited washing (cold water + dryer). There's a bit of stretch above and beyond what cotton normally does (from the nylon or lycra I believe) but you can't tell unless you're putting the shirt on.
As for fit - fits me perfectly. I tend to be more of a large in the shoulders and a medium at the waist, but this shirt is great for me. Def more of a fitted look but NOT jersey shore douchey type fitted.
EDIT - +1 year and shirt is still going strong. No rips tears, etc. I've washed cold and warm, tumble dry medium

Comfortable, and surprisingly good quality
Color: 31260 Green, Size: Large
Super comfortable and stretchy, worked great for my chicken little costume. I’ve washed it about 5 or 6 times now and it hasn’t shrunk or gotten pilly or anything.

Good fit, but thin material and average color
Color: 31230 White Black, Size: 3X-Large
The sizing on this T shirt is accurate. It fits well and feels comfortable in terms of shape and length. The cut is true to size, so I did not have any issues there.
However, the material is much thinner than expected. It feels lightweight, which may be fine for hot weather, but it does not feel very premium or durable. I was expecting slightly thicker cotton based on the description.
The color is also not as nice as it appears in the pictures. It looks a bit dull in person compared to the online images.
Considering the thin material and overall quality, the price feels a little high for what you get. It is not a bad shirt, but I expected better value for the money.
Overall, the fit is good, but the material thickness and color quality could be improved.

Loooove these shoes!
Size: 7.5 Wide, Color: Chestnut Brown Faux Leather
I have these in several colors, and they’ve become a true staple in my wardrobe.
The Amazon Essentials Women's Belice Comfortable Slip-On Ballet Flats are exactly what I look for in an everyday shoe—simple, versatile, and comfortable right out of the box. The slip-on design makes them super convenient for busy days, and they pair effortlessly with everything from jeans to dresses to work outfits.
They’re lightweight but still feel supportive enough for all-day wear, and I appreciate that they don’t require a break-in period. The fit is generally true to size, and the variety of colors makes it easy to stock up and rotate depending on the outfit.
Overall, these are reliable, easy-to-wear flats that offer great value for the price. Not flashy, just consistently comfortable and practical—which is exactly why I keep coming back to them.
