Checking labels is something I've always done, usually to avoid falling into the trap of buying a 'cashmere' jumper to get it home and take a closer look at the 2% cashmere, 98% polyester tag in frustration. I find that sale time is the time where this happens most, it's the frame of mind that you're in a hurry and therefore have to make a quick decision. Heck no you don't. There is all the time in the world for you to decide, wander around and think it over and be sure of your decision. If you're not, ask them to hold it for you, get a coffee and take your time. More often than not sale items are not refundable so it's better to be sure! I also find it helps to have a clear four or five items in mind that work beautifully with your potential new item and making sure it fits a hole in your closet that NEEDS to be filled. Separating need from want is an art form, one I'm yet to master to be honest. Speaking of sales, keep your eyes peeled we're coming into one big sale period - the temptation is real ladies.
