Hello. They have a semi-loose fit so you shouldn't need to worry about sizing up on this item to accommodate a lightweight layer underneath. We would recommend ordering according to the size chart but we can always help with an exchange or return too, if needed.
Thank you and please get in touch with us at 1-800-783-8326 or email@example.com if you have any questions at all.
