Most Helpful Girl
Implants and the extreme push up bras, plus some photo shop and some stuffing probably help. I think the girls look great, but the majority of them do not have really big boobs. I am a DD and I cannot shop at Victoria's secret. Their bras do fit small. In Victoria Secret bra's My room-mate is a D, and I am a DD+ in a regular bra, put us together and I am like 5x bigger. So ya, their bras fit much differently than normal bras.
I wouldn't worry too much about it. The majority of the Victoria Secret models are not D's, they are more likely A's, B's and some C's. Which would be normal for someone of that size. Push up bras add a few cups sizes. Especially when they add padding on top of that which some of VS's bras do.
Back in Tyra's day, she would have had C's or D's. But now the models are more fit and skinny so they are smaller.
There are some genetic freaks though. I lose weight and my boobs stay. But I am also a broad person. My shoulders, and hips are both wide. The boobs look normal for my size, and I would be wide at any size. And genetically I am just made to have big boobs. Some people are smaller framed, like most of the VS models and would have naturally smaller boobs. It's all about body type and proportion.
They just make do with what they have naturally and then add the bras in that make them look bigger.
Try doing some ab exercises. It will make you stand up taller and won't change your boob size. But still give you the look of a slimmer stomach.
