Very functional and spacious!
Color: Upgrade-apricot, Size: 16 Inch
I wasn’t expecting to love this backpack as much as I do, but wow —it’s everything I wanted and more. The apricot color is soft and pretty without being too “girly,” and the fabric has a nice matte texture that feels durable yet lightweight. It doesn’t have a plasticky smell at all, just a clean, new bag scent right out of the packaging. The compartments are super well thought out. I can fit my 16-inch laptop, chargers, skincare pouch, and even a change of clothes without the bag looking bulky. The back padding is surprisingly comfy, especially during long airport days, and the straps don’t dig into my shoulders. It sits well on my carry-on handle, making it the perfect travel companion. If you’re into functionality and aesthetics, this is it.

One of my Favorite Blouses!
Color: Navy Blue, Size: Large, Color: Navy Blue, Size: Large
This is the perfect top when you want to have a little dressier look than a t shirt, but you still are dressing casual or you could even dress it up because the material is just so nice. . I bought my usual size which is large. It’s a little bit loose, which I like, but not oversized. It comes down to around mid rear end . It is a half sleeve or almost a half sleeve, so it covers the batwing area. It is a high crew neck, but not uncomfortable. It basically stays wrinkle, free almost all day long and after you wash it, it is ready to wear. Speaking of washing, the garment says to put in a separate bag and wash in the machine. I did not put it in a separate bag because I didn’t read the instructions, but I had no problem afterwards. It does say hang to drive which I always do anyway, and the blouse looks brand new after several washings. The top is very well-made, very department store like looking. I purchased two of them, the navy and the white. The white is a little sheer, but not too bad that you have to wear something underneath it because it is a loose fit, it looks put together. The price was great as I got it on a deal.

Super cute summer T-shirt!
Color: Black, Size: Small
Surprisingly cute! I thought it looked kinda neat and it turned out pretty great! I got a white one too! The fabric is cool and lightweight. It's different and I like that! It does wrinkle but no biggie. I was looking for a longer sleeve T-shirt and this exceeded my expectations!
