is it too early to wear your halloween costume, even if it is September?

After speech last week, we stopped at Target.  After SJ decided on his toy purchase, he had an immediate need to look at the Halloween costumes.  He LOVES Halloween (I do too, so I guess he gets that from me!)!  He started to look through the racks of kid's costumes.  He found some Mario Bros. costumes.  He started to decide between Mario, Toad or Waluigi.  I told him we had to see which one came in his size first.  Obviously if the costumes were too small, that costume would be eliminated.  They didn't have a Mario in his size, but they did have Toad and Waluigi.  He chose Waluigi.  I know it is early to buy a Halloween costume, but I learned my lesson from last year.  Last year, I waited until 2 weeks before Halloween to look for costumes and his size was hard to find.  He was so excited over the new costume!  It was $20, which was not a bad price for a costume.  He wanted to open it in car, but I told him to not put it on until we got home.  He did, however, where the hat that came with it on the ride home.  I kept laughing to myself as I saw his reflection in the rear view mirror.  As soon as we pulled in the garage, he ran upstairs to his room to put it on.  Thank goodness, it fit.  His smile was so big!  He was so happy.  Every day last week, he wore that costume in the house.  I told him he couldn't wear it outside.  I am afraid it will get ruined before he gets to wear it to school for their Halloween party.  So I calculated how much it is costing me per wear so far.  It is about $3 a wear as of this week.  By the time Halloween rolls around, it will probably by about $0.25 a wear.  Maybe it is too early to wear your Halloween costume, but seeing his happy face makes all that logic go right out the window!
