This lot does use some store content. There is no custom content used. There is also a seasonal marker so be sure to visit when the seasons change to get all the new styles :-) (use of the seasons wall decals, suggest you download first before installing this lot) they are found here http://store.thesims3.com/setsProductDetails.html?scategoryId=13793&index=0&productId=OFB-SIM3:56412
If you need to edit the lot, there are steps to take due to the use of the seasons marker. You will need to use cheatcodes to access the marker. BE SURE TO CLICK "LOCK COMMON" WHEN DONE EDITING.
I hope you enjoy shopping at your new Clothing Store!
