I love that shape on others, but.... I'm an apple and personally I find it challenging to wear. It seems to highlight my middle and make me look bulkier. I tend to like empire waist tops or ones that are a tiny bit fitted around the middle, then flare out. That little bit of shape, higher up, helps me create a waist.
Updated: So funny reading other people's perspectives. I am busty but have relatively smaller hips and tops like this make me feel like I look pregnant. The one time I felt good wearing them was when I was pregnant! I love them on my friend, who is a classic pear because she can wear them looser on the top and since she has a slim middle, they don't add bulk. But that's just my eye and I'm in the minority here, I think.
I think it must come down to how they look on you, so there is no escaping it. You're going to have to buy it and give it a try!
