Help me find a dress (34 k US)

Hello I have always been so sad I can never find a dress (or even shirts) that I feel pretty in. They all are made for women with C cups it seems. They tend to all have the weird boob inseams that don't even go past half my book, the the waist like is also never under my boobs. It makes me so so sad. It seems no stores have things for me, and also online the only options are for plus sized women (also that assumes small cup sizes given the waist measurement). Thanks <3
