Sexy Costumes & Lingerie FAQs

What are the best sexy costumes for Halloween parties?

Classic favourites like witches, maids, nurses, and catsuits are timeless. Choose a look that fits your personality and comfort — then add stockings, gloves, or accessories for extra flair.

Can I wear lingerie as a Halloween costume?

Absolutely. Many of our costumes double as lingerie sets. Pair them with sheer tights or a robe for party comfort, then keep them for romantic nights later.

How do I choose the right size?

Use your regular U.S. dress size and check individual product notes. When in doubt, size up — most designs use flexible, stretch-friendly fabrics for a flattering fit.

What should I buy to complete my costume?

Stockings, fashion tape, nipple covers, or simple accessories like chokers and gloves are all easy ways to finish your look and make it uniquely yours.
