i will be showing in english: hunter jumper, pleasure, equitation, and jumpers also. i heard for hunters they don't accept the zip back.

also is this a good show coat, im paying for it myself so tats why i'm on the cheaper side of everything http://www.doversaddlery.com/product.asp?pn=X1-40242&ids=798948612 most sizes i've seen start at 8 and im probably a 4 my mom said. and since everyone in the review says that the coat runs small so maybe the 6th would be perfect. um im going to local schooling shows first but if me and my horse are any good we might move higher. so would these be suitable for the higher. or should i buy it for now and then purchase again later. thanks and happy holidays.
