Nothing quite pulls the blood from under my fingernails than presumptions about women who wear red lipstick. Especially the one suggesting men don't like it, honestly that would incentivise it more than anything for me but I'd say the opposite is true. I do sometimes wonder if the effect of wearing uniforms in Britain affects how comfortable one is to step outside a comfort zone defined externally. With many, I feel it's an all or nothing attitude, the complete disregard of it is a defiant one (like the punk movement), it's what makes London style interesting but it also makes it less of a cohesive one.
I needed some diagrams to explain, so excuse the rough sketching and can't be arsed to start up the scanner once more, but it's in order to demonstrate body shape is not a 2D thing, but most of us stand in front of a mirror and tend to draw our conclusions from that.
Predominantly it is where you are predisposed to put on weight (3D) and your skeletal structure (2D mostly). What we consider a stereotypical pear looks quite bottom heavy from the front, from the side they're pretty flat. Frontal pears, if you will, tend to look quite slim from the side and on top, especially if they're long waisted and tall, you hardly even notice it. CdM is one I suspect, I don't really have a good picture for it as she dresses and poses too well (pic 3 is the closest I can find) but she's quite narrow on top and only adds on extra weight when you're past the midsection and further down the bum which is practically flat until you reach the bottom of it.
A sideways pear will see excess weight pack on higher, but not as high as an apple, it sits predominantly in the lower back, bum, and lower abdomen area, even if they're not short waisted, optically they become one. The more weight you pack on the more it moves inwards and makes the waist area as a distinct feature almost disappear. I've tried to capture it in the sketch somewhat but I assume this leads to some spinal issues too as in compensation it'll contort forward to rebalance the centre of gravity which could explain why you get that look of an apple.
