I know alot of people expect their bridal party to pay for at least some things.

Personally, I chose to pay for everything for my bridesmaids and the groomsmen including suit hire, dresses, makeup and hair. My bridesmaids already had shoes and jewellery they could wear so neither of us had to buy that. One of my bridesmaids still bought us a present and my other bridesmaid (my sister mind you) didn't get us anything (not even a card!). The best man also bought us a present. Even my mum and dad didn't buy us a present (a whole other vent!).

I don't think you've done anything the wrong way. If I was asked to be a bridesmaid, I would assume that I would need to pay for my outfit, hair and makeup unless the bride said otherwise. And yes I would still get a present even if it was just something small.
