Too tight for the first 3 months, fine after that
351542
Got a medium and tried to wear it when I first started breastfeeding.  It was way too tight, so I bought a large, and that was also too tight.  After my milk supply regulated itself I didn't have any problems with it particularly, I just am not a fan of wireless bras.  Overall, I would just recommend buying a wired nursing bra for going out and a sleeping nursing bra for staying in.  This was the worst of both worlds for me :\

I gave it 3 starts though because it seems well made and if it's what you're looking for then it could work well.  I just never felt comfortable in it.

Thought at first they were too small but after wearing them for a few hours the leather really loosens up.

When I first put these on, I thought they were the most insanely comfortable things I had ever put on my feet. The fit was snug, but somehow that was good -- there was no rubbing, they felt almost like a second skin. However, the snug fit caused problems in the long run. Pulling on and taking off the shoes apparently causes stress on the narrower cross-pieces of the shoe, resulting in breakage. After one summer of wear, the shoes are still kind of wearable, but the cork "webbing" (for lack of a better word) is broken in several places. I like the shoes enough to give them another try, ordering up one size. But I had already ordered a bit large the first time. Normally, I wear a 7 or a 7 1/2, so I went with the 38, which their sizing system says is equivalent to a size 8. This time I'll order a 39, equivalent to an 8 1/2, a full size higher than I normally wear. So, if you order these, order big!

This is my second pair of Earth shoes. My first pair were similar in style but with a tongue and a velcro flap. My first pair lasted well over 6-months of wearing nearly every day to work though they did take a few days to wear in and stop pinching. I wear an 8.5 / 9 and for these I ordered an 8.5. They seem tight across the toes like my first pair, but unlike my first pair, these did not stretch out. Going on 2 weeks of wearing, 10 hours a day, and they are still too tight.

Really nice quality and fit, comfortable material. This worked well for the first 5-6 months of pregnancy until it got a bit too tight as my tummy grew. I can see myself wearing these after the delivery as a regular dress, tho.

The strap over the arch is tight at first, but after a few wears molded perfectly to my foot.  I have a narrow foot so this was not a problem.

Shoe fit wonderful for about a month, then start loosing their shape and got very loose. Is there a way to tighten them back up?

These were a little tight across the ball of my foot when I first got them, but they stretched a little bit and now fit fine.

Not so confortable at the beginning, I had to fill them with socks to stretch them, but they fit better after using them for a while

I loved these, but they stretched out after two months of moderate wear to the point where they no longer stay on my feet when I walk. They also started out so snug, so I know it wasn't a sizing issue. For the price, I would expect better.

these are great. I got the 3 month size and at 3 months they still fit my baby but are getting tight. I bought the cream ones in 6 months size and they fit with a little room.

It got loose after 3 months of use. Probably some soft metal is used.

I have been hesitant to write this review, but after a few months of using these shirt stays, I felt the need to do so. When you first put them on, they are tight and definitely keep your shirt firm and tucked in.  However, as the day goes by, the clamp that allows you to either stretch or tighten the straps begins to give.  By the end of your day, the shirt stays have become loose, not having the same firmness from the beginning of the day.  Ultimately, this causes your shirt to begin to become untucked, despite me using all 4 stays; 2 on the front and 2 on the back.

I love these for my 4 month old son. He's not walking but needs something warm for outside time this winter. They stay on through all of his kicking and moving. However, order up a size or two. I ordered size 6month while my son was still 3 months and they were perfectly his size. Now (at 4.5 months) they are too tight.
