I happened upon JT Posh by accident when I was searching for IC London, and found out that they had a popup store in JT Posh near Toast and J Majors. Because of the name, I guess I always thought it was a men's store, but it is a delightful consignment shop. Many consignment shops in town either are targeting an older audience, but at JT Posh there are tons of cute, on trend styles in all different colors and patterns.
The store is also merchandised more by category than sizing, which makes it a little tougher to find what you want, but the stylish way they have it merchandised it makes it feel more like a specialty boutique and more fun to shop. It's not overloaded with merchandise, but the large size of the store allows for a wide selection. They offer lots of nationally known brands and designers that you know and love as well as a large section for maternity clothes that are actually stylish. I will definitely be back!
Bottom line: 4.5 stars for shopping (no rating yet for selling).
