Despite its shipping fee (increasing shipping fee with increasing purchases, what kind of sorcery is that though?! Shouldn't we be entitled to free shipping....), I would not hesitate to order from this website whenever my friends ask me to join. Forever21 online provides a better range of clothing as compared to the stores. The accessories are also sometimes not seen in SG stores.
One thing to look out for is the exchange rate (a little goes a long way) and the sales item!!! :-)))
Shipping takes 3 weeks though. Not worth it for the hefty shipping fee heh :-( but for the range of items available, exceptions can always be made.
