I know many of us struggle with what to wear and when to buy clothes that fit, knowing we're likely just passing through that size. I have been a Democracy Jeans fan for years. Their "ab-solution" tummy panels aren't miraculous, but they they do a decent job, they're good quality, and super comfortable. They also come in a variety of lengths, which is appreciated as a fairly tall person.
Well, I've discovered that I have a new reason to love them. I have several pairs in size 16 that fit when I really should have been in an 18. They also fit (and look even better) now that I'm solidly in a size 12! I get that it feels good to see a smaller number when you put on a pair of jeans, but it's also really nice to not have to buy something new knowing that I'm just visiting this size. I typically buy them from Amazon - they have a decent selection and pricing. They're also available at Nordstrom Rack, Macy's and elsewhere. They're not the cheapest option out there, but given this versatility I think they're a worthy investment!
Note: I have no personal connection or investment in the brand - I just don't want to gatekeep knowing how challenging this aspect of weight loss can be.
