Great blouse for work!
I purchased this red blouse as a Prime deal for Valentine’s Day. I wore to work with black pants. I think this is a great work blouse and intend to buy it in more colors. It is cute, not very formfitting, but still has a V-neck.
I would say it runs slightly large. It is also long in length. For reference, I am usually a large or XL because I am busty, but the large was plenty big and I was wondering if I could fit into a medium... If you want a more flowing top, this is definitely a great choice. I think this would look great with white jeans also and perhaps even tied at the waist.
As some reviewers have said, it does wrinkle easily. wWhen I got it from Amazon, I ironed it inside out, and all of the wrinkles came out. Perhaps, if you were sitting all day, it would be very wrinkly in the front. I sit for my job, but I did not tuck in the blouse - I kind of had it flow away from my body and it stayed mostly wrinkle free all day. I plan to buty in more colors!

Very nice
Size: Large, Color: Blue White Petal
Perfect length and fit and doesn't cling if you like a more relaxed look. I purchased 3 of these for work and I love them. I can wear them with khaki cropped pants and sandals, very cute. After washing and line drying there hasn't been any shrinkage and the fabric stays nice. Perfect for warmer weather climates!

Sizing seems to be different depending on color!
Size: Large, Color: Mini Leopard
Ordered in Mini Leopard in Large and Pink in Medium. The Mini leopard was too big and the Pink was to small! Decided to return both and order the pink in large. That fits!!! Sizing is different in different colors! Like the style and hopefully it will wash okay. Kept the pink, large! It did come extremely creased!
