Simple and Trendy Clothing Brand Logo, 40 Love

I'm looking for a eye catching and fashion conscience logo, but simple. It is to be printed on the clothing of a new brand called 40 Love.

Although the clothing will be marketed to tennis players (hence the 40 love) it should not scream tennis. I want it to appeal to every female fashionista. It needs to be simple and in one colour so printing it small onto a polo shirt collar looks good but looks equally good as a large print on the front of a t-shirt. My initial idea is to use a heart with the number 40 in it and possibly forty love written below the design. I am also toying with the idea of incorporating the website http://www.atthenet.co.uk into the design, but I can't think how it might work. If you have any ideas great. This will strictly women's and girl's clothing so keep it on the girly/womanly side. The colour is not important but I would like the design to look good printed in black, pink, baby blue, and other fashion colours to compliment the clothing.
