Tone your legs.
I’ve always had bigger thighs so I definitely feel your pain although from a size 18 to 10 a handful of years ago my thigh progress was slow, it was almost a joke between my trainer and I in measurements days. I realised my legs didn’t look that bad and training increased my self esteem and confidence in certain clothes.
I mostly wear sports leggings though and recently I’ve bought some lovely casual and active leggings from
www.lucylocketloves.co.uk and I like them a lot ... not like me to wear much kore than black tbh haha
