Leah:

We were scrimping and saving at the time our first was born, so she 
had a lot of handmedowns from cousins, for which I was very grateful, 
but they were sometimes not what I'd have chosen.  And I remember the 
pleasure, when finances improved, of going out and buying what I (and 
perhaps daughter!) wanted.  So, I think there's a subconscious 
pleasure for Molly in being able to indulge herself with Harry's 
dress robes and not worry about what the family will have to go 
without to afford them.  So Ron's entitled to some feeling of being 
miffed- but not much.

Are we meant to read anything into maroon? It's a sort of purplish 
colour isn't it- does it go with Ron and Hermione crowned, Weasley is 
our King and so forth?
