I did all of my maternity and nursing gear shopping here and absolutely love it! Thyme Maternity across the street seemed to be the same in quality but has a smaller selection and is a bit more pricey. I have alway gotten great service here and there always seems to be great sales. In the month right after I had my baby my husband went to get me nursing tanks but the sizes he got were too big and when he went back to exchange them he said is was super easy and they were incredibly helpful. I have also gotten nursing shirts as gifts from there and had to exchange sizes and the gals were so nice about it. In some stores you sort of get the eye roll when you have to go return or exchange things or it even feels like the sales people are trying to make it difficult for you, but that has never happened to me here! Great place to shop :)
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.
There are many options in maternity shirts from Old Navy. There are tanks for layering, nursing, or for use when the weather is warm. There are also long sleeve and short sleeve maternity T-shirts in many stylish colors and patterns. For those looking for a special occasion outfit, or something that can be worn to work, there are also tops that can be worn with dress pants or skirts.
Staff are helpful, but the store is tiny and you find you're being followed and/or watched with every item you stop to look at. Thyme Maternity as a whole is not the most fashionable maternity wear. They definitely try, and some items are okay. But the cut of pants and tops tends to be very loose and flared, and so it doesn't necessarily reflect more current styles. Good for some staples, but if you're looking for something more "trendy" try H&M at the Eaton Centre.
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
