FAQ Image

Do I need to wear a pad or tampon with them?

Our Thongs work for very light flow, or as backup protection for a tampon or menstrual cup.

How do I wash my Aise BASE undies?

Rinse the gusset in cool water before washing in the machine with your regular laundry. Hang to dry where possible - it saves energy & prolongs the life of your undies! Just make sure they’re fully dry before reusing. Otherwise machine dry low.

The small runs small

To things must run small I ordered according to the size chart and it was too small for me. The other styles fit me perfectly in the same size but not this one.

Would not recommend this product. Just okay.

At most stores I am an 8/10 or medium across the board, but sized up to a large based on the reviews saying that this style runs small. Even with the large, I still find it to fit a little tight. The material is not as stretchy as I want it to be. Also got the Base Shorty and I liked that style better, but in the future I think I will get my period underwear from a different place.
