True Religion and Rock n' Republic Jean Size and Uggs?

I just bought True Religion size 2 (25-26) and Rock n’ Republic size 26 and Uggs Boots Size 7. I was wondering if they would fit me because I am about 5’3" 120 Ib and I usually wear a size 2 when I buy jeans from Express and usually I wear size 2, Abercrombie probably about a 2-4. And as for shoe size, I wear a size 7-7 1/2 so I’m wondering. I would try all those on but I bought it online. Can someone help me? Thanks a lot!!
