1. Longer bobs can be bland if too blunt. Stacked layers in the back add dimension.
2. A bob can't be too layered, or it's not a bob. Gwyneth's bob here is more edgy because the stylist thinned out the ends with scissors or a razor.
3. Ask the stylist to make your bob a touch shorter in the back.
4. This cut works on straight and wavy hair (you'll see what I mean in the next images). It's a versatile cut because you can wear it wavy or flat-ironed.
