There are many late 18th and early 19th century images of Welsh men and women wearing low-crowned, broad-brimmed hats.
Henry Wyndham noticed broad-brimmed hats in Wales, other than in Pembrokeshire:
In the other parts of Wales, the women, as well as the men, wear large beaver hats, with broad brims flapping over their shoulders. Nay, even some of the better sort of people affect this covering; for I afterwards met, at Llandrindod wells, three old ladies of the neighbourhood, who supped with us under the shade of their beavered umbrellas. ….

H.W. Bunbury produced a number of portraits of Welsh peasants including:
Peasants in the Vale of Llangollen 1781. The woman has a ‘bowler’ hat, and the man is wearing a low-crowned, broad-brimmed felt hat.
‘Welsh Peasants’ showing a large brimmed, low crowned hat, 1780s.
Mrs Morgan noticed the same in south Pembrokeshire:
Their hats are rather larger than the present fashion, and lower in the crown; but they are much more convenient as a shelter from both rain and sun. Under the latter I suffer daily with my little beaver, and envy every Welsh woman I meet.

John Evans noted that the women of north Pembrokeshire wore ‘a large, broad brimmed, high-crowned, beaver hat’ while the women of the south of the county sometimes wore a beaver hat with a shallow crown.

Similar hats appear in pictures of working women and the gentry at the end of the 18th century.
