There’s the final episode of The Way We Were, Abi Morgan's The Split returns for a third season, Joe Lycett hosts the new run of Travel Man: 48 Hours in, and BBC's Murder in the Badlands concludes . . .
Pick of the Day
The Way We Were, 9.35pm, RTÉ One
The final episode of the second season looks at how people dressed in Ireland as the 20th Century progressed into the 21st.
Each decade of the 20th Century saw its own Holy Communion fashions, bridal and wedding fashions, work wear fashions, partywear fashions, weird underwear trends, teen and youth fashions and outlandish fads.
That ranges from the birth of teen fashion in the 1950s to the 1960s when rising hem lines caused scandal.
In the 1970s there were the hippies at Carnsore to the more colourful glam rock look. Disco and finally the punks rounded-off a truly divergent and largely androgynous decade.
The 80s saw the debs ball phenomenon and the consequent democratisation of formal wear, the appearance of the New Romantics and, later in the decade, the baggy bugged-out stylings of the Acid House generation.
