I used to buy for dd occasionally. Clothes and coats: they are okay but coats were on the small side despite my dd being a petite girl we still needed to order size up. Clothes: not at all special. We bought some leggings in matching colours with the coat and they shrank at the first wash (40 degrees), became too tight rendering them useless and I didn't bother trying to complain.
Having variety of nice colours for coats for instance and having colour-matched accessories and clothing items is good in theory but that's about it.
I buy and sell a lot on eBay. It holds value very well and so is worth selling. Clothes last ages and we had a pair of girl's trousers that did for DD, plus 2 more families - 5 children in all and are still in good nick.
I buy new or on eBay and never pay full price - ever.
