Nice quality but questionable fit!
Color: Navy 09, Size: Large
I recently purchased the Alex Vando Mens Golf Shirt in size Large. The fabric quality has a good feel to it — it feels smooth, breathable, and the moisture-wicking seems to work well during light activity.
However, the sizing and fit were inconsistent. I ordered a Large, but when I tried it on, it was somewhat tight and fitted around the mid-section, despite not saying "slim fit". I would say I am average size: 5' 9", and 195 pounds. I were a size Large in 98% of the clothing I purchase. This was more like a size Medium - Long. That said, the shirt is also very long! Like, abnormally long. If you're tall (over 6'), this shirt will be perfect. But for anyone else, it won't fit quite as nice. I had to return it as I think an XL would be huge on me!

Sexy jacket!
Size: XX-Large, Color: Blue
I want to first say that the jacket looks exactly as pictured the color is very spot on it's not too washed out and not too blue. I bought it for my male partner, It really gives him the rugged look without making him look intimidating or too much like an emo boy. I'm thinking hipster style.
Secondly, you have to size up if you are intending to wear this jacket on top of a sweatshirt or anything thicker than a t-shirt. I'm so glad that I read reviews before purchasing this because if I had bought his size it would have fit him but he would not have been able to wear a sweater or sweatshirt under it. My partner is tall and about an XL in sizing. The jacket stops just at his waist and accentuates how tall he is. Sleeve length is perfect.
I will also say that it's not super thick, it's a great fall jacket just good enough to stay warm in brisk weather. This is more of a fashion piece than it is a coat.
Something that no one mentioned is there are two large pockets on the inside of the jacket that my boyfriend loves because he can now hide snacks in them.
This jacket honestly gives me New York Street fashion vibes and I love it so much I plan on stealing it from him time to time.
