In the interest of being more environmentally friendly, we are moving away from including cups with every tank/bra order because we've found so many are being thrown out. Don't forget that the cups are interchangeable! They'll fit in all your bras and tanks that accommodate removeable cups.
I think this answer is a bit specious. Sure you can reuse the cups but if you are just building up a lululemon wardrobe and you work out every day, that means you'll have to hand wash the cups that night to be able to wear a tank with cups the next day. Addionally, the cups are not nearly as durable as the tanks. After a while the edges get ratty and they get wrinkles so I think it's good to have spares to keep on hand.
I'd like to take a mini poll and ask you guys:
Do you throw away your bra cup cookies?
I haven't thrown away a single pair yet and I think I have bought something like forty or fifty tanks that came with the cups. I do use the cups when I wear my tanks out of the house, especially with the Luxtreme tanks. I am saving them because after a while the cups get wrinkled (I don't hand wash them) and some of the edges are getting tattered so I know I will end up throwing some away because of wear and tear. Most of the time I don't ask for cups when I buy a tank in the store because I have so many at home.
I think the best solution is to add a check box to the order to ask people whether they want the cups. However, I think with cups should be the default option on all the luxtreme and white tanks. The material is so thin it shows everything.
