Not silly at all! Especially not for $5! However, since looking at size 6 shorts from a 16/18 perspective can be very daunting (I was there 10 months ago!), I recommend stashing those 6s somewhere and only pulling them out every once in awhile. I have a drawer full of goal clothes that I'm not going to look at til spring. What I do recommend is getting a piece of short term goal clothing, like a size 12. You'll be amazed at your awesomeness when you're able to fit, and you'll be very glad you got them when the 16s keep falling around your ankles and the 6s are still too small
