I ordered this halloween costume for my 4.5 y.o.,  an avid Olivia the Pig fan.  Although my expectations are never very high in terms of the quality of these types of purchases, even I was disappointed when this costume arrived.  The shirt and jumper are one piece and not two (which is clearly indicated in the costume description and not a problem itself), but the jumper straps aren't even fastened to the front of the jumper.  Instead the straps are sewn onto the shirt about an inch and a half above the top of the jumper.  In addition, although we bought the small size, which is supposed to fit sizes 4-6, the elastic at the top of the leg warmers is too tight around my daughter's thighs.  She is 39lb. and 42", and at the low range of size 5 for most clothes.  I've noticed other websites offer a "deluxe" Olivia costume that has a seperate shirt and tights instead of leggings.  I think we are going to give it a try, even though it's priced at about $40 and appears to be manufactured by the same company.  I recommend anyone else looking for an Olivia costume do the same, rather than trying to save $10 like we did on this costume.
