The advantages of under the bump are that they aren't so bulky under tops and to combat exposure or to allow you to wear a shorter top you can always wear a belly band or long vest top under your top top. Under the bump tend to work better for skinny, stretchy style jeans as the stretch in the denim will hold the jeans on your leg as supposed to having to rely on the waist band only.
I worked this job part time for a year before deciding to return to work full time after staying home for 5 years with my kids. Part time hours were fine; pay was minimum wage. I was repeatedly offered the store manager position but the hours would have been less than ideal (working every weekend and several evenings a week) and the pay offered was brutal. All associates were pushed to sell specific products and these sales were tracked weekly. The review process was horrible- you could rate 'excellent' in every aspect, but if your store wasn't meeting the sales budget, you 'failed' your overall review.
Ok so I HATE maternity clothes... or I should say hated... I bought my first pair of maternity jeans yesterday from primark of all places and I am literally in love! They are still nice and skinny and fitted but so comfy around my bump - check out my maternity video on what I purchased here; https://www.youtube.com/watch?v=r3bLjGSHMZE&index=3&list=UU-DxGKz7B0xh_zSDzgnL2cw
If you've ever been pregnant, you know that maternity jeans can be a real saviour for your wardrobe. As your waistline expands, everything starts to not fit quite so well (sob!), and it can get uncomfortable—not to mention expensive. But if you have some decent denim options at your disposal, you can at least wear some of your looser tops over your bump. And there are some brilliant jeans that can help with that.
