Popularized in the 1950s, illusion necklines allowed modesty as well as showing off a little skin.  Albeit it was opaque but sexy and demure since baring your arms and shoulders in church was considered sacrilege. There's been some news on the 'you can see right through it fabric front '. These days illusion--that transparent stuff found in a few varieties of sheer fabric is available in stretch tulle, power netting, organza and chiffon to name just a few of your options.  Designers (me included) are using softer and stretchier fibers for the max in comfort . Add lace over top for that genuine all time traditional favorite bridal look.
