Like a fist to the face of the traditionally insipid, female-fronted rom-com, Bridesmaids marks a departure from the oft-derided norm, not by being brassy or crude (OK, there might be a sizeable helping of the latter) but because of its authentic humour, credible character dynamics and the foregrounding of female friendships over romance. It is also wildly funny.

The sturdy, healthy, almost glowing attractiveness of Ruby Loftus, her reddish curls partly tamed by a green hair net, her face punctuated by bright-red lipstick characteristic of the 1940s, her blue overall neatly complementing her red shirt, and her expression intense and concentrated as she screws a breech ring as part of the manufacture of the Bofors gun at a factory in Newport, is a famously captivating image of the Home Front in the last world war.

The remarkable thing about Caryl Churchill, Max Stafford-Clark has said, is that she is "completely new, every time she comes out of the box". Watching the first act to his revival of her most celebrated work, which Stafford-Clark revisits for Chichester Festival 29 years after he directed its Royal Court premiere, you feel Top Girls isn’t so much being lifted fresh from that box as bursting through the lid.

Freud’s West Hampstead house is tied up in a cat’s cradle of thick rope. The rope is the same colour as the brick, a deep orange but with a sheeny lustre. It makes the house look not quite real, a Brobdingnagian doll’s house transplanted to this unsuspecting corner of leafy west-London suburbia. It’s an uncanny impression heightened by the pristine condition of its squat, many-windowed façade.

Kelly Reichardt’s quietly radical vision of the Wild West is a slender, provocatively ambiguous work and the antithesis to the genre’s muscular action-packed epics. It’s a western which aligns us with those who don bonnets rather than Stetsons, and which favours quiet pluck over showy heroics. With a narrative shorn almost entirely of incident, its existential, quasi-religious minimalism recalls Waiting for Godot.

Feminism is a dirty word. Ask anybody. Do they want to be tarred with the label? Do they, hell. The word still carries connotations of man-haters. Even today’s young women fighting against harassment in tube carriages, horrified by the easy access and the violence of pornography, even they complain that fessing up to being “feminist” lays them open to ostracisation and isolation. Yet with rates of violence against women, unequal pay, the lack of women on boards, pregnancy as a cause of job dismissal, sex trafficking - rightly or wrongly, feminism is on the march again.

A maypole greets you on entry to the Serpentine Gallery; don’t expect a cheery celebration of spring, though. Nancy Spero’s installation Maypole: Take No Prisoners II (2008) is a scream of rage against violence and its hapless victims. Dangling from coloured ribbons, dozens of decapitated heads hang in the air like an explosion of shrapnel. Mouths gape open in pain and terror - or is it hatred? One can’t be sure, since some seem to be spitting venom from bloody tongues as though, even in their death throws, they are intent on spreading a gospel of vengeance and destruction.

Louise Bourgeois died last year at nearly 100, a revered figure: survivor of the Surrealist movement into the 21st century, a pioneer of autobiographical expression, whose fame came only late in life. Tracey Emin, by contrast, found fame early, coming to the attention of the general public in Charles Saatchi’s Sensation show at the Royal Academy while she was still in her thirties.

Fashion and conceptual art come together, sometimes awkwardly, often provocatively, in the Royal Academy’s third and final annual GSK Contemporary exhibition. Instead of celebrating glamour and excess, designers and artists – as well as those, such as Helen Storey (1) and Hussein Chalayan, who have successfully made a fashion to art crossover - take on big themes: cultural and personal identity, conformity and freedom, globalisation and the environment. The exhibition explores the shifting concerns that have preoccupied these practitioners over the past five decades.
