What kind of shorts are they (eg. spandex) and how long are they?
Where did you get them from?
Why do you wear them and if not why not?
I always wear black spandex shorts under mine. They have about a 4" inseam so they are nice and short and don't poke out below my skirts.
I brought mine from Forever 21 and American Apparel. I love the black nylon/elastane spandex shorts from AA the most as they are the most comfortable and love the high waisted feel on them..
I just like feel securely covered so I can be comfortable and confident in my dress or skirt without having to worry about someone seeing my underwear.
