If a super-luxurious bridesmaid gift idea is what you're after, then jewellery is the obvious choice, but there are affordable options, too. A personal gift that your girls will absolutely love, if chosen well, jewellery can be a gift they'll wear forever. If your bridesmaids all have different tastes, don't be afraid to buy them each a different piece of jewellery, just be sure to stick to a similar budget for each.
