Well made, warm.
Color: Brown, Size: X-Large
A heavy yet soft flannel shirt. Nice on a foggy or light misty day. Flannel is a bit loosely woven but well sewn. Size reflects its lable. Its become a 'got to' shirt this fall.

Quality look
This is my second purchase of this shirt. Soft, thick, good quality. Usually worn open with a tee underneath. Sizing is normal and a good length. But it could also be tucked in. Looks great!

Great shirt
Color: Khaki, Size: XX-Large, Color: Khaki, Size: XX-Large
Wonderful shirt. Bought this for my husband to wear for family photos and it fit great, wasn't scratchy and he was so comfortable in it he actually wears it to work sometimes even to this day. I would buy this brand again. It washed it before he wore it, I didn't notice any shrinking.

A good First Communion suit
Size: 6, Color: White, Size: 6, Color: White
This suit looks and feels really nice even though it’s not 100% linen. My son is an average size 7 year old, but I got a size 6 so that the fit would be nice and snug and not loose and baggy. It was the right choice. Comes with a bow tie which is nice, a tie (which is very cheap and poorly made) and a pocket square.
