help! I need to have a white evening dress! where can I buy an affordable dress PLUS SIZE!?

You can search online for plus size clothes but if course there is definitely with a riak involved. U nees to know your aize and add some allowance if you are going to purchase online. Alternatively, you can google to see where to puchase plus size clothes. Where i know of is Cotton On, Topshop, Marks and Spencer, etc ...

There's a group called Plus Ladies Shop on Facebook with legit sellers and the clothes are of reasonable prices. Just make sure to do a quick legit check before ordering from anyone on Facebook. I was able to buy some great stuff from the wonderful ladies there.

H&M has a wide variety of clothes from different sizes. :)
