Both have their lingerie pros and cons. Online shopping, you need to study the sizing charts diligently because they actually are all different but there's no chance of running into anyone, say a former teacher (it's happened and I was in highschool at the time*shudder*); in store, whether you're trying on or not, you can tell if it fits. I prefer in-store shopping, especially at La Senza lingerie. my boyfriend was looking through a VS magazine and saw something he liked...i like it also but saw something else i liked and i dont know which i like better....so lingerie what do u think of these and which is sexier... btw i am 21 years old. in black with the garter belt lingerie (not shown) ( i believe the second link is to the picture under this one):
