Spend the money. I'm a 32G and I've found that Fantasie and Freya make nice bras, they will run you $125-$200 for a bra, but you'll never go back. Their bras are very supportive, but also attractive.

I actually did this myself because I was so desperate for a bra that fit. I removed the hooks from the back of my bras and ended up cutting 2.5 inches from each side (the bra was a 38F and this was a little while back, now I'd actually need to cut off another 0.5 for it to fit better but there's just not enough space left) and then sewed the hooks back on. It doesn't necessarily look the nicest BUT it's worked very well for the meantime and is actually supportive! :D

You can find those exact same bras here for much less. www.biggerbras.com/

I know this thread is a little old but I wanted to add that because I'm a 36H, I have to order bras or get them at a Boutique or Nordstrom's. The first thing that I would do is to get measured by a certified bra fitter. Different bras from the same company will fit differently so it is nice to be able to go to a brick and mortar store that actually sells the size you think you will wear. The bra fitter will know/should know what bras will work best on your body. Granted this can be tough if you don't live near a store that sells your size (I live 4.5 hours from the closest store that sells my size)!!

The brands that I like to wear are Elomi, Fantasie, and Panache. They all have pretty bras, t-shirt bras, exercise bras, etc...They are more expensive ($50+) than the Bali bras that I used to wear but didn't fit into (boobs were spilling everywhere). When you wear a bra that fits properly, you look thinner though. It's worth it.
