Tattoo on the thigh

I'm looking into getting a thigh piece but I'm super nervous because I have bigger thighs and am also in the process of getting a gym membership to lose some weight and get fit. If I get the thigh piece now and lose weight in my thighs or even tone them up will the tattoo look bad? I know if you gain weight the tattoo will stretch but what about losing or toning up? Kind of a stupid question but curios.
