Let's talk bras

I don't think I've ever found a bra that I've been happy with. I'm a 36DDD, is that the same as 36F, I usually just see DDD not F? Pretty much all the bras I've seen for my size have straps that are way too wide. It makes me feel like I'm 60. I'm only 25 and I want to wear fun pretty bras but have never been able to do so. Also they are almost all ugly in the larger sizes, and either black or white, maybe a beige or red if your lucky. It drives me crazy! Also to find one that actually fits you properly you have to pay twice the price of a regular size and they still wear out just as fast as any other bra. If anyone has any recommendations for me here in Canada or a web site that ships to Canada I'm totally open to suggestions. I just wish Victoria's Secret went up to DDD. It would make things so much easier.
