Fantasie are the best for me, I wear nothing else, they do a great moulded push up t shirt bra and a more natural moulded style t shirt but both will give you a great shape and don't be too scared by the moulded bit - it won't add to your boobage.
I second statisticallychallenged's suggestion. I've been wearing that bra, in various. Oil ours (and there's a lacy version too) for years. It gives a v good shape and is comfortable. Not too hoiked up....quite natural.
