Great father's day gift
I bought it for my husband for father's daypl0k from our two years old son.
Sweet and simple book for a father to read to with his baby or toddler.
Each page has a different daddy and baby animal with a simple and short phrase and cute pictures.
My son picks this one out to be read to him from his dad as part of his regular rotation.
I highly recommend

Cute Basic Tank That’s Easy to Dress Up or Down
Color: Taupe, Size: Small
This ANRABESS sleeveless tank top is a really cute basic to have in the closet. I bought it in 3 colors. I like the fitted ribbed style because it gives it a little more shape than a plain tank, but it’s still simple enough to wear with just about anything.
The scoop neck is flattering without being too low, and the slim fit makes it easy to tuck into jeans, shorts, or wear under a jacket/cardigan. It’s one of those tops that works for everyday outfits but can also be dressed up a little with jewelry or nicer pants.
The material feels comfortable and stretchy, and it has that casual summer look without feeling sloppy. I’d say it’s great for warm weather, layering, or just throwing on when you want something easy but still put-together.
Cute, flattering, and comfortable — a great basic tank that I can see myself wearing a lot.

Great, well-fitting basic!
Color: Beige, Size: Medium
I love, love, love these basic tanks. They fit true to size. They’re really soft and comfortable and they’re such a great value. I have them in at least five or six colors. They look great on their own or under a cardigan.

Light weight, not thick or bulky, versatile, and perfect!
Color: White, Size: Small
Throw out all the tank tops you own cause this is the only tank top you will need from here on out. It is absolutely perfect. Let’s just say they understood the assignment. It is form fitting and pairs perfectly with lightweight sweaters that might be slightly sheer or even the new crochet type of open sweaters that need a tank underneath. It is the perfect stretch, perfect material and dressy enough to be worn on its own and upgraded with some jewelry and some classy jeans and has just enough sheen to look dressy and not like you’re wearing a workout top. I love , love this and it is my go to tank!

Comfortable, flattering wardrobe staple
Color: White, Size: Small, Color: White, Size: Small
I’ve tried a lot of basics, and this ANRABESS sleeveless scoop neck tank exceeded expectations. The fabric feels soft and breathable with a nice amount of stretch, and it has a flattering fit without being too tight or restrictive. The scoop neckline is classic and versatile, making it easy to layer or wear on its own. Stitching and construction appear well made, and it held up nicely after washing with no shrinking or loss of shape. Great quality for a basic essential, and a piece I can see reaching for often. Highly recommend.
