I'm a bit of a convert to Ivy, and wear their tops for work and at home. They are great for daytime to evening wear. The black Nancy didnt disappoint. Its the right amount of slouch and can be dressed up or down.
I find them durable, the colour and shape always lasts, and they are really well made.
Check out the size guide as i do move between their sizes, but ive followed the guide and never had to return anything.
