i remember i got my tna fleece suit taken in from a medium to a small ages ago LOL. yeah when those tna suits were in. anyways i think u can go to any alterations place and they will take it in for u. but it may be pricey since yur material is jeans.

mine was fleece and jus to take in the sides of the jacket was like $25 and the pants was like $25 =[
