Jeggings vs Denim-effect leggings.Both lack the bulk of normal jeans- buttons, zips, pockets- and are therefore more suitable for layering on top of.
For those with problem area stomaches (hello me) they are both far more flattering than normal jeans, and are also more comfortable and won't dig in- goodbye muffintops!
Jeggings: If you don't like leggings but like their positive features, this is a good denim look. It still counts as a jean.
The crotch area is a lot more appealing than that of a legging. Though the waistband may not be attractive to you, you can wear shorter items on your top half with ease.
They don't look quite as natural under dresses as leggings do.
As they have the shilouette of leggings and are not stretchy, it can be hard to find a pair that fit your stomach, thighs and calves without them getting stuck on the way up or being lose in an area or two, it's a question of trying different brands. Miss Selfridge ones are no good on my calves but Dorothy Perkins ones are perfect.
Denim-effect leggings: They're different to the norm of the black legging and are thicker and less transparent- like upgrading from 20 denier tights to 60.
Are very good for putting under dresses- whether it's for a dressed down look or you have a lot of walking to do.
It takes a brave person (preferably with a flat stomache) to pull off wearing them with a short length top half. I shudder just thinking about the crotch situation..
They're more flexible than actual denim so tend to be more comfortable. They also tend to be less stretchy than other leggings though, so have less give.
Unfortunately don't always look that great around the ankle area so are a little difficult to choose shoes and socks for. They tend to show up the socks underneath a lot.
