Well...Lace is A-nol & Est...and BI is A-nol,A-none,Est & Cops.Sure they can be worn together,but why?
Many people,including myself,get great effects with Lace & Cops! ...I have a Sugared Pure spray with Lace that I wear with Occo Red,for instance.
I believe in wearing one _blend at a time...of course Cops goes with anything
ETA...yeah,what Luna said...hah 5 people can post while I am still typing.
