Bracknell & Wokingham Swimming Club's Willis was something of a surprise package as he booked his London Olympic spot at the first time of asking in March, swimming a best-ever 200m breaststroke time of 2.09.84 minutes to win the national title.
That display ensured that earlier this month he felt like a pampered celebrity at Loughborough when he collected his Stella McCartney-designed GB kit for his debut Games.
And with the kit and the Olympic spot in the bag Willis admits he is counting down the hours before he can make his first appearance at the Greatest Show on Earth.
"The kit handout was amazing," he said. "I was a bit anxious going in, with big shoulder and long arms, but everything was just amazing going in to see the gear, and you can see what the girls are going on about with it being like having a personal shopper."
