In the good old days it was a rule of thumb that you measured your inside leg from crotch to the floor and subtracted 10 inches from that figure to give you an approximate frame size to start looking at. Your frame mentioned is about 22.5 ins, so your 33" less 10" would bring the frame into your size. However frames are not as simple as height. The length of the top tube also plays a part in frame fit.
Having said all that proper frame sizing seems to have gone out of the window. Titchy little frames and 4 foot of seat post seem to be the norm nowadays so perhaps someone more versed in modern kit can advise you better.
Good luck with it!
