Just going through my cycling clothes since it looks like it is going to be warm enough to ride this weekend. My spandex bibs and shorts have enough stretch that they will still work, but man the cycling jersey's are definitely not form fitting any more. I don't mind buying regular clothes as I shrink, but man this stuff is expensive! Well time to shave my legs so the I am not completely ostracized by the other riders.

I cannot run without spandex type underwear......

and although I have stopped loosing weight, I am still dropping sizes because exercise keeps changing body shape and muscle/skin tone....

Cycling clothing has special flat stitching to avoid chaffing, I think I will just buy new

Okay I have very little knowledge about cycling clothes. Read that as none. Could you try something made by Under Armour? I've seen several knock off brands as well as Under Armour at TJ Maxx and Marshalls. I know Under Armour is meant to be worn very tight and close to the skin. Those might be cheaper then buying cycling clothes during your interim sizes.
