Very nice. Runs small
Color: A-white Flowers Bf290, Size: 3X-Large
You’re beautiful shirt! The fabric is soft and very comfortable to wear. My only concern is that I find it runs small to size. I ordered one and then I ordered one a larger size and that fits better. I received many compliments on this shirt. I recommend this shirt for its comfort.

Perfect for classy evenings or comfortable running around town
Color: Pattern Kah, Size: Medium
I favor wide-leg lounging pants in large sizes for their comfortable fit, which strikes the perfect balance between loose and baggy. These pants exude elegance, making them ideal for both social gatherings and quiet evenings with my spouse. The fabric flows beautifully and keeps me cool and dry. Its breathability is notable, and I appreciate the vibrant color, soft texture, and high quality, particularly during the pleasant late afternoons and early evenings typical of Southern nights.

Love these pants
Color: Apricot, Size: Large
These wide leg palazzo pants are super nice! The material is very lightweight, making them perfect for summer. They’re incredibly flattering, comfortable, and I absolutely love the fit. The drawstring waist and pockets are a great bonus! For reference, I’m 5’10”, 170 lbs, and ordered a Large — they fit perfectly. Highly recommend if you’re looking for stylish, flowy, comfortable summer pants!

Love! New favorite pants!!
Color: Apricot, Size: Medium
I really love these pants! They’re extremely versatile. I wear them to work in professional attire, then come home, throw on a t-shirt, and wear them to lounge for the evening. They’ll even be great over a swimsuit on vacation. Bonus points for having pockets! They have been durable enough for my phone and keys without them dragging the pants down. When I first received them, I was surprised by how thin and somewhat see-through the apricot pants are— to the point that I considered returning them. I’m so glad I didn’t! They are insanely comfortable. Don’t let the reviews about being see-through deter you. Work around it! One day of wear and you’ll see why. I prefer to wear these with shirts that tuck in the front and cover most of my bottom in the back due to how see-through they are in this light color. The comfort is worth it! They are long for someone my height, 5’2”. I wear them with a Sofft sandal that has a thicker sole that adds a little height. This prevents them from touching the ground without me having to pull up on them all day. I can easily and comfortably wear them a little high on the waist to help with the length, as long as I’m wearing the thicker-soled sandal (or a heel). I don’t wear heels, so it’s thicker soled shoes for me! I don’t feel these are going to be the most durable pants and expect to replace them more quickly than other pants- but I do expect to get at least a couple of good years out of them. They are lightweight and cool, perfect for summer and spring. I don’t see myself wearing them to work or anywhere outside during cold winter weather. I read the reviews and ordered a size down. I’m normally a large, size 8-10, and the medium fits wonderfully and is very giving. If I liked a tight pant, I probably could’ve gone with a small. I will absolutely be purchasing them in other colors! With this apricot color you’ll need to wear white or skin-colored seamless underwear. I took one star off for being somewhat see-through. Outside of that, they are easily 5 star pants. ⭐️⭐️⭐️⭐️⭐️ For the $20-$25 price, get them and thank me later!!

Great quality for the price!
Color: Apricot, Size: Small
Great palazzo pants! I was looking for something to wear in Florida to a graduation but did not want to be too hot. These pants are versatile and very flattering. So comfortable as well and no wrinkles! The length was perfect for me at 5'2" and they wash very well. I purchased slip shorts to wear underneath to avoid the dreaded panty line / crease, etc. and the slip shorts smooth everything out & make you look seamless!
