Uniqlo/+J Blazer - Looking for similar material & fit

[darkchocoacai]

For those who are familiar with this blazer, can you please direct me to other labels that are very similar in fit?
The material is pretty awesome and I'm looking for additional pieces that work super well with pretty much anything.
I wear it in a size small. Only complaint I have is the pits are a smidgen too tight, otherwise I think its great all around.

What do you guys think of the regular blazers that Uniqlo offers?

Thanks
