My bridesmaids are all wearing strapless dresses, but this has raised some concerns as far as being dressed appropriately for the mass. I'm looking for a cover-up idea that isn't tacky (think HS prom shawls) or old lady-ish (many boleros/jackets at David's Bridal). The cover-up is only for the church and won't be worn once the ceremony is over unless the girls so choose. Any suggestions/tips/help would be greatly appreciated!!!!
