I think I see now that you want to express especially the woman's clothing got really wet. Then you wouldn't say she threw her drink into the woman's face. You'd write it in such a way that you emptied the drink all over the woman and soaked her dress.
We've given you plenty of verbs to choose from for this. However, the action of flinging and throwing usually sends the liquid into the air and it would land haphazardly on the woman. If you really want to get the dress wet, I'd say you poured your drink down the front of her dress or all over the woman or on the woman. That action would definitely soak the dress in front, which is what I think your objective is.
Just saw your post, Panj. Yes, I agree with you, as I just wrote. I see now the intent was to make sure the dress got soaked, not just the indignity of getting a bunch of booze thrown in the face.
