I bought this costume for my husband to wear for my son's first birthday party.  The costume top is a velcro closure in the back but for $24.99 you can't beat it!  My son lit up immediately when he saw my husband try it on and I am sure it will be a big hit at the party.  If your having a Yo Gabba Gabba theme for your child's birthday I highly recommend DJ Lance Rock makes an appearance!!!
