Classic dress at a great price
Size: Medium, Color: Black Ivory Geometric
I was shocked, in the best way when I received this dress as the material is thick and heavy. I was looking for a dress that I could take on business trips that was comfortable, stylish and didn't wrinkle. This dress checked all the boxes. It's a classic style that will never go out of style.

Runs smaller than my regular size.
Size: Large, Color: Hot Pink Leafy Floral Ditsy
Medium weight fabric and decent quality. Tight fit across bust and under arms and also waist. I am not a big busted woman although I am not so many inches different from bust to waist (it gapped at waist upon sitting. I had to exchange it for a bigger size. So my experience leads me to belive that this manufacturer sizes smaller than what I would expect from expensive clothing. For the price is a good choice if you remember to go at least one size up from your regular size.

Perfect comfy on the go or everyday wear! Preschool?
Size: 3T, Color: Dusty Rose/Pink Text Print/White Rugby Stripe
Sounds silly but these Amazon essentials shirts are better than some other name brands. I bought same brand for myself. These shirts have been camping, dirty, and stains come out, they keep their shape and their color. I absolutely love them. Moms & Dads, if you want inexpensive and still decent shirts I recommend these. They come in a 3 pack, there’s no itchy tag, they are loose fitting, they don’t shrink, and the colors are true to picture.

Perfect
Fits perfectly. True to size. Good quality and lasts long. I love how long they are, it’s not too long but they have added length to the bottom a little bit which makes it nice for toddlers. Will buy again. Worth every penny. Color choices are great.
