The website generally is too 'princessy' for my taste, however that's a taste thing - however you should be aware that some people will not shop in Prince and Princess shops. That said the clothes look nice and there's good clear photography.
However there are some repeated grammar mistakes throughout. I think it would really be worth your while to have an experienced web proofreader take a look at the site.
In general:
You need to work out the possessive apostrophe:
Girls' clothes - many girls
Girl's clothes - clothes for one girl.
Not Every Word Needs A Capital Even When It Is Product Descriptions. It makes things very hard to read.
You have stuffed your 'About Us' with so many keywords that it's unreadable. Your 'why shop with us' is much clearer.
Generally you have quite a lot of 'writing' - which you don't need. You don't need, for example, to put an adjective on every category of footwear - Stylish Footwear For Little Boys, Stylish Footwear For Little Girls, Stylish Unisex Footwear.
It's punchier to just put Girls, Boys and Unisex. We already know we're in footwear because we've clicked through there and we can also see the pictures which tell us we're in footwear - do you see what I mean? Try not to add words which describe the images, use words to reinforce the images.
HTH.
