There are basically two strategies for dressing big breasts:
1) Buy stretchy t-shirts and try to dress them up as best you can, and
2) Buy clothes that are designed with your curves in mind.
I alternate between the two strategies, personally. Not everybody can afford to buy special clothes, so it's useful to have some ideas for dressing up stretchy t-shirts.
My favorite two accessories for curvy ladies are belts and scarves. Usually, I use belts to define my waist, but the gathers in this shirt helped to do that on their own, so I chose this belt which lies lower down on my hips. If you're petite or slimmer hipped you will probably prefer this location for belts.
I was always totally against skinny jeans until I found these. I still wear boot cut or flared jeans most of the time but it's fun to experiment with a different style once in a while. And yeah, between the jeans and the belt this outfit probably emphasizes my hips more than I would usually go for. But I liked it anyway. And it's good to break the rules every once in a while.
Can I just say that scarves are awesome. Really really freaking awesome. They are seriously not given enough love by curvy ladies. I think many women with big breasts are afraid that a flowing, colorful scarf will draw too much attention to their chests. But I don't think that's true.
The way I tied this particular scarf, it creates a deep 'V' shape, breaking up the shape of my breasts without having to show the cleavage of a plunging neckline. This would also be a great strategy in the winter, when you want to wear a higher neckline for warmth's sake.
Scarves also are great for covering up cleavage if you have a shirt that's a little bit lower cut that you would like. They have an elegant, carefree, bohemian feel that I just love. If, like me, you crave soft, flowing fabrics, but need structure to flatter your shape, they are a good way to add that soft flowy feel in.
Oh, and they're cheap! You can find pretty scarves for a few dollars at all sorts of thrift, consignment, and vintage shops. So it's easy and inexpensive to create a collection. Within a few months of realizing how awesome they are, I had a whole basket full.
