Looked beautiful
The merchandise was what I needed. The delivery was not accurate however. The order was dropped off 3 apartment doors away from where I live. I had to guess where it was after the emailed delivery notice.

It works
Manageable to dress in, and pre-tied relieves the burden to tie it on manually every time.

Very happy with purchase. Great value, looks and quality.
These shirts are incredible value for the money. The fabric is of fantastic quality, a nice thickness, not see-through (appropriate for work/office attire), stretchy, breathable and wrinkle-free. And it isn’t flimsy like you’d expect in dress shirts in this price range. The colors are just like the images - accurate. The Shirts feels and looks far more expensive than the listed prices here. I like these so much that I ended up buying 8 of these in different colors. Definitely recommend these ! Note on Sizing: I had first ordered the AI-recommended L size, and although I was able to wear it, it was hugging my body, and figured that it would fit me well IF I was in perfect shape. If you have a few extra Lbs like I do, or if you like a little bit of room in your clothing, I’d recommend a size higher. So I ended up returning the L and ordered the XL. So if you’re slightly out of shape, go with one size higher. If you’re in good shape - these run true to size.
