Your final divorce decree/custody papers will control.  Most impose a requirement on both parents to take care of the child at their expense while in their custody- with exceptions for things like medical care-- those bills are often required to be split by the parents.  It is extremely rare to see a divorce decree with provisions for clothing.  If your decree doesn't include a "special dress provision", then you send what you can and want to with your daughter.  Make it clean and cute.  To cover yourself, you may want to snap a photo of what you pack-- so when he tries to say later that you dress her "like a pauper", you have a visual illustration for a judge.  Just because he pays child support doesn't give him the right to tell you how to dress her or how to spend the money.  Child support isn't just for clothes-- it covers food items, school supplies, utilities, housing, and all of the other stuff to raise a kid.  Unless your decree says that he can dictate how you spend that money, then you spend it on what the money needs to go to-- the basics to make sure your daughter is adequately clothed and fed.  If he wants to see her in frilly outfits, then he can fork out the extra money to do so..... or he can increase the amount of child support that he pays so that you can afford the extras.
