You cannot feel them when you wear the dress. There's a remote control with several options from staying one solid colour (Red, Green, Blue or White) to strobe, flash or fade (where the colours keep changing and fade into one another). The back is lace-up and is the only part of the dress that doesn't light up.
Due to the lace-up back, you can comfortably wear it whether you're a UK size 10 or 12 (US 6 or 8). Re:damage, the dress has one small area on the hem that is frayed (see photo) but is in perfect condition other than that.
The bit of frayed hem is roughly 3cm wide x 5cm long. You can surely have it stitched together but I don't know anything about sowing so I don't know how easy it would be to do. Either way, there's a layer of tulle-like fabric on top so the hem isn't very noticeable, and the lights on it still work.
It has been expertly dry cleaned and then re-tested, and it works perfectly. It was only worn for 2 hours! The dress also comes with a hoop underskirt (which, fyi, is really loose so I had to use a ribbon to tie it to me) and several extra batteries, charging cables and two remote controls. Don't hesitate if you have any questions!
