Agree with all the previous suggestions, have a look at recommendations but when I was MOB a few years ago I couldn't find anything I loved. My chum had the same quandary, she was tiny and what she wanted she could find, she was advised to check out a wedding dress designer who was local, who also made MoB dresses he is amazing.
I saw a fabulous dress that was over 2k, a dream dress, which I added to my pin board when I was showing him my thought he said he could "copy" the style.
He found suitable fabric (bright over the top) matched up the lacey bits which were a red. Made me a sort of dinky fascinator, and added some lace to the back of my colour matched shoes . My dress was bespoke to my shape totally unique. The cost 25% of the one I saw.
So check out in your area if there is anyone around like this guy, if nothing grabs you from the suggestions.
Have fun and good luck
