How to DIY Halloween Costumes on a Budget

A great way to save on Halloween is to make the most out of everyday items. Use these tips to easily pull together DIY costumes on a budget.

Find the right wig

Hair is half the battle of nailing a costume. An accurate wig can transform clothes you already have to look like your favorite celebrity or character.

Disguise yourself with temporary ink

Face and body art will take your costume to a ten! Use temporary tattoos to get the look of swashbuckling scars, mermaid scales, or haunted doll stitches.

Get creative with makeup

Eye-popping shadows, pigmented lipsticks, and colorful false lashes are your secret weapon to making a costume look complete. We like BH Cosmetics for their unique color selection and bright payoff.
