The fluid fit trend is great but if you have reached such a major accomplishment, losing 30 lbs, I have to imagine you may be hankering for clothes that show off your body? Also more structured/fitted pieces do have a way of making you mindful to KEEP the weight off. And yeah it also takes a long long time for the brain to catch up to the body, and realize whoa... I don't need to hide away in baggy clothes...
When I lost weight (this was 20 years ago) I kept wearing baggy clothes (sized down but still baggy, ya know?), until one day a very kind and wonderful friend grabbed the back of my baggy pants (which would be totally ON TREND right now!) and said... "we need to take you shopping... "
So yes do the trends but you might also want to add to your list a few select items with structure, more fitted, to celebrate your hard-won work:
- perfect jeans -- NOT relaxed, not BF's
- a fitted structured blazer that goes with everything.
- BELTS!
Just my two cents!
