The VS sweatshirts and sweatpants are my guilty pleasure! And every time I order them online, I am rarely disappointed. The sizes are always consistent, the materials are so soft, and the quality is absolutely top notch. My other VS indulgence will have to be their perfumes haha.
There's actually a VS store near my house, but I love to order the items online instead because when there are sales (and trust me, VS has really good sales), the products are so much cheaper than they would be normally in Singapore. And the delivery is so quick that the parcel will arrive at my doorstep after only a few days!
When using VS' online store, I think it's okay to buy generic stuff like sweatshirts, but for bras and undergarments, it's better to try it on at a store then buy it instead of getting it online. My friend bought an undergarment set online once and found the bra was a little too small for her although she had ordered one in her usual measurements.
