You could be a 'tweener... but you could try sizing down one more. I am a size 28 in Dior, a size 27/28 in Diesel and a 26 in APC New Cures. My true waist measures ~30" or a little over. With 28 Diors, I can get them buttoned/clasped with some effort, but they feel snug. However, with size 27, I couldn't pull them up past my thighs for the life of me back when I tried them like a year and a half ago.
I don't know if I would be in the same situation now as I was back then, but if I am... then I'm a 'tweener and would have to settle with sizing down 2.

Good thing I wear jeans everyday. I can rotate.
