an 8-10 for my daughter. she is normally a small 8. it is so tight she cant wear it, we will donate it to someone in her group. it is great quality and great price. just know that you need to order a size bigger. that this pass is only an advantage if you intend to experience many of the sights in paris. this means that you plan to visit all the major sights, then it is an advantage if not, then we do not recommend it.
