The 43-year-old actress - who is dating Justin Theroux - believes she looks her best when she is dressed casually and loves borrowing the actor`s shirts. She said: "I feel sexy in my jeans and wearing my boyfriend`s t-shirt." Jennifer - who revealed she and Justin are currently house-hunting in Los Angeles so they can "live between both coasts - admits she loves Justin`s style, but insists he hasn`t influenced the way she dresses, despite what her friends think. She told the new issue of America`s InStyle magazine: "First of all, he has great style - it`s very specific, and it has been his style forever. Has it influenced mine? No, but I know people say it has. `Oh, look, you▓re dressing alike.` And I think, No I`m not. I`ve had this jacket for three years!" The former `Friends` star - who was previously married to Brad Pitt and has been romantically linked with stars including Gerard Butler and Vince Vaughn - says she has learned more about what she looks for in a boyfriend as she has gotten older. She said: "Having experienced everything you don`t want in a partner over time, it starts to narrow down to what you actually do want. "As I get older I realise what qualities are important in love and what suits me. And what I won`t settle for."
