Pretty in PINK

What I really love about Victoria's Secret is that I can go there with my 14 year old sister and not feel uncomfortable. I (a 22 year old) can go look at the lace and frills while she can go in their PINK section. I don't have to worry about her finding anything that I would want. I definitely do not want my little sister wearing lingerie yet. The PINK department of Victoria's Secret is age appropriate. She can find anything from sweat pants to summer dresses. 

PINK offers all the same things, such as bras, panties, swimsuits, and sleepwear. The only difference is that they cater to the younger crowd. I remember when I was her age and I wanted to be like the older girls that I saw shopping at Victoria's Secret. However, when you're that age it's daddy's money and daddy gets to determine where the money is spent. Of course he's not going to want his 14 year old daughters buying lingerie. 

So in about five years she can look over in my section. HaHa. 

I tend to go in the PINK section at times as well. I love the flip flops they carry. I also purchase my yoga pants from there. There are still really good sales in the PINK section. Especially around the summer when the summer dresses are most popular. 

So my question is..... Should I be the "cool" sister and let my 14 year old sister shop for lace and frills as well? Or should I continue to try to keep her as innocent as possible?
