Is buying men's jeans in bulk from overseas a smart idea?

I am considering buying several pairs of men's jeans directly from online sellers this month. I have compared different sellers' prices on eBay, Alibaba, and Amazon before considering this option. Most of men jeans cost $25 to $40 per pair but the minimum order is often 10 to 20 pieces. I would need to buy 10 pairs to get the best price and then keep 5 pairs for myself and sell the other 5.

I've got mixed reactions about this plan to buy jeans in bulk from overseas:

• Is the quality of $30 jeans from online sellers comparable to $60 jeans from major retailers?

• Are the size measurements on overseas listings accurate or I will end up buying a cloth that is bigger or smaller than me ?

• What is your overall opinion on buying clothing directly from foreign manufacturers?

I want to save money on jeans but I am not sure if buying in bulk from overseas is a smart idea.
