Great holiday sweater!
Special Size: Wide Ribs, Size: Large, Color: Lake Green
Good looking shirt! Bought for husband for our holiday pictures to wear over a collared shirt and it looked high quality, was soft and felt comfortable despite it being 70 degrees

solid old style docs construction
i am a medium to wide-ish 7.5 in women's, that typically wears an 8 for room. these fit like a wider, roomy 8.5 women's. that is fine because i intend to wear them with thicker socks and for long walks.they are immediately comfortable, and do not feel like they will have the typical brutal break in period. very stable and fitted around the ankle, yet not impossible to pull on and off.
they are so handsome, and meet my expectations.
