I find it very dated. I would never use it because lots of older people around here pronounce it like “[name_f]Shirl[/name_f]” or “Shur-ull”
However, if you like it and/or it doesn’t sound dated to you go for it! It is likely to come back in style when a little girl named [name_f]Cheryl[/name_f] today is in her 20s and everyone will be jealous of her stylish name!
I find it really dated the only [name_f]Cheryl[/name_f] I know personally is in her 60’s but I also think of the English singer [name_f]Cheryl[/name_f] who’s only 33, and actually got the name to reach the top 1,000 in the UK back in 2009 (there were 11 born in 2015). [name_f]Cheri[/name_f] doesn’t chart at all, but I would use it before I used [name_f]Cheryl[/name_f].
The problem with [name_f]Cheryl[/name_f] is that it isn’t old-ladyish…names popular with great grandmothers are coming back in fashion, and that tends to be the cycle. [name_f]Cheryl[/name_f], however, is a mom or maybe a grandma name…dated, but not yet ripe for coming back into fashion.
[name_f]Cheryl[/name_f] was never overused, though, and, if you love it, go for it! I think flowermae may be correct…it may get popular again when your daughter is a young adult, and suddenly she’d feel young and chic for having such a fashionable name! 
I have always liked the name [name_f]Cheryl[/name_f]. I don’t think it is dated at all. And if people feel it is dated, then there is your nickname option.
Sure, it’s dated. But someone had to boldly use [name_f]Emma[/name_f] to bring it back. Now we see Ediths on this site. Phonetically it sounds pretty, it would be familiar to people, but not commonly used with babies. It’s an interesting choice.
