I'm sick of buying jeans which seem to fit perfectly when first tried on but then get too loose after a few days' wear. I recently read in Cosmo that jeans should always be bought two (!) sizes smaller for this very reason which seems a bit extreme.
I'm wondering whether to size down but then worry I'll end up with a permanent muffin top! I generally wear Topshop jeans - usually Leigh but have been recently converted to Joni (less problems with these due to mega high rise) and Jaime.
