Another problem is back lighting. In 1980, when 19 year old Lady Diana Spencer (the future Princess Diana) was dating Prince Charles, she innocently posed for some photos with her kindergarten students. Little did she know that her sheer skirt, back lit by the sun, became transparent revealing her form in a definitely "unladylike" manner. Anyway, the photo became world reknown. (Google it if you must.) The moral of the story...if you don't own (and wear) a slip...maybe you should!
Or check out some lovely vintage slips like this one.
Remember the following tips:
~Wear skin tone undergarments with white clothing so they don't show through.
~Wear black or navy undergarments with dark clothing.
~Don't let your slip show through a skirt slit. That's why many slips have a slit...it should line up with the skirt slit.
~Visible undergarment straps are not a fashion statement...they're trashy! That's MY opinion!
~Need a little curve control; try a shaper slip
