Thank goodness I got married in 1999 when sleeves were still popular. They throw women of all different shapes into sleeveless and strapless today. If the women feel confident about it then that's fine but I've heard of stories where the bride has had to search the rest of the country for a wrap, stola or bolero and then that's been a compromise. Sometimes having a dress tailored doesn't cost that much more than buying one off the hanger. If you're in good time, then maybe having a vintage one modified can be an affordable choice. Choose a natural fabric that can be dyed afterwards if you don't like to wear white or light colored dresses.
