Whether it’s a tip-top secret or a glimpse of nip, a slip is rarely a good thing.

Unless you’re talking about Your Slip Is Showing, a company offering flirty underthings that are meant to peek out from underneath a dress or skirt.

The whimsical creations add flair and take any outfit from boring to wowie zowie. Black ostrich feathers and rhinestones turn a basic black sheath into sleek formalwear. Embroidered lace and silk organza transform el cheapo into vintage glam. And intricate red chiffon roses put a feminine twist on anything they are beneath.

Go crazy and throw one on over pants — it’s damn near impossible not to look sexy no matter how you wear it.

But be careful, he may try to slip it in.
