What is ur hip circumference tho?
If u wanna get pretty tight and lifted hip, You'd better choose the size according to ur hip size.

You can feel small to wear at first but its because of the compression power. 
So you'd better get use to this fit and you will feel better in second try on.:)
Anyway try it on once more, and if you still feel uncomfortable, send it back to our office and update me with the tracking number.

And the round trip shipping fee will be charged. Please note the exchange/return policy here : http://m.en.vinaandco.com/article/faq/3/5953/
