Of course, sequins have to get into this whole trimming thing. If you want to add some eye-catching glitz, but rhinestones would be a little too much, you can’t go wrong with sequins.
Sequin trim can be wide, narrow, flat or three dimensional. It can be stretchy, or rigid. Stretch trim is best suited for dancewear, bodysuits – anything that’s going to stretch with wear, obviously.
Always sew sequined trim on to your costume, don’t glue it. You can’t be sure how the adhesive will reach to the plastic sequins and, besides, I find glued-on trim likes to fall off at the worst possible time.
Sequin trims can cost as little as a dollar a yard for simple single-row trim and can go as high as you can imagine, depending on how elaborate it is – and sequin trim can get very elaborate indeed.
You don’t want to put sequined trim through the washer or the dryer. Your washer will shred it and your dryer will melt it. It’s unlikely that it’s safe for a dry cleaner, either, although you could try hunting down a dry-cleaner in your nearest theater district – they’ll be used to handling costumes with all kinds of shiny things on them – and ask them their opinion. Otherwise, hand wash anything embellished with this kind of trim and lay it flat to dry.
