Long rounded hem Rainbow Snakeskin Print Top Shiny Silky Size L

I cannot find the size tag or information about the material. I assume it is a rayon / polyester. It is stretchy and silky feeling tee that is quite long. I have worn this top with black or grey tights and it looks great. White and grey snake print background with pops of pastel blue, yellow and pink. Good condition despite all the mysteries. It's long. Purchased in 2018 at a small boutique. I know it's a large but the tag is not there. Measurements: Chest across is 20" Length is 29"
