Is there an age limit on sexiness now a days? Does the limit stop at your 30s? Even 40s? I beg to differ. Today's modern women could never be too old to be sexy and confident. However, there is a difference between dressing outright sexy and dressing sexy with a touch of class--with age in mind of course.
For instance, take a simple slim business pantsuit that the model in the the photo is wearing. It is very sophisticated and stylish but teases us with a deep V-neck, exposing the cleavage area a bit. The model is not a teeny bopper obviously--this is a grown woman we are staring at. To me, she is dressing as an adult professional, but is adding a sexy swag to it. The pantsuit is not baggy--it perfectly fits her slender build. She looks modern and chic--classy but sexy and tasteful. She is not wearing a bra, but if I were to guess she is wearing sticky nipple coverings. The dark shades speak that she means business.
In summary, (to my older women)--don't ever put out your "inner sexy fire" just because you get to a certain age. There are many ways you can dress in style, have sex appeal, look your age, and not look like your grandmother in the mirror. Step up your game a bit, and find what works for you!
